Generalized Atrichia

Generalized atrichia means a person has little or no hair on most or all of the body. “Atri-” means “without,” and “-chia” refers to hair. In many babies with this condition, a thin layer of newborn hair appears at birth, but it falls out in the first weeks or months and never grows back. The scalp is usually smooth, and eyebrows, eyelashes, and body hair are also absent or very sparse.

Generalized atrichia is a very rare genetic condition where a baby is born with normal hair, but loses almost all hair in the first months of life and the hair never grows back. Hair loss affects the scalp, eyebrows, eyelashes, armpits, and the rest of the body. Many children later develop many small, firm, skin-colored bumps (papules). These bumps are tiny keratin cysts in the skin. The main cause is a change (mutation) in a gene called HR (hairless). The condition is autosomal recessive, which means a child is affected when they receive one changed HR gene from each parent. It is often mistaken for alopecia universalis (an autoimmune disease), but generalized atrichia is not autoimmune and steroids, minoxidil, and JAK-inhibitors do not regrow hair in this disorder. Genetic testing of the HR gene confirms the diagnosis. Lippincott Journals+3PMC+3orpha.net+3

What is happening in the body

In generalized atrichia, hair follicles form before birth, but soon after birth the cells inside the follicles shut down and die too early. The follicles stop making hair and later many small keratin-filled cysts can appear in the skin. Because the follicles are permanently inactive, usual hair-loss medicines do not work. A skin doctor can often tell the diagnosis by history and exam, dermoscopy (a close-up lighted lens), and genetic testing. Dermoscopy may show clusters of white dots and no growing hairs, which helps tell this condition apart from alopecia areata. Lippincott Journals+1

The most classic form is congenital (present from birth) and is often due to changes in a hair-growth gene. In one well-known form called atrichia with papular lesions, tiny skin-colored bumps appear later in childhood because hair follicles have not developed normally. Some people have isolated hair loss only. Others have hair loss with features in other body systems (for example, teeth, nails, sweating, or bones) as part of a syndrome.

Generalized atrichia is not the same as temporary hair shedding or pattern hair loss. It is usually lifelong and does not respond to typical hair-growth treatments. A careful history, examination, and a small skin biopsy or genetic test can confirm the cause.

Other names

• Congenital atrichia

• Hereditary atrichia

• Atrichia with papular lesions (APL)

• Alopecia universalis congenita (used loosely in some texts; strictly, “alopecia universalis” can also be autoimmune and acquired)

• Generalized congenital alopecia

• Hairless (HR)-related atrichia (when caused by variants in the HR gene)

Types

1. By timing

   • Congenital/early-onset: hair present at birth or very fine “lanugo,” shed in infancy with no regrowth.

   • Acquired: rare; hair is lost later in life and does not return.

2. By cause

   • Isolated (nonsyndromic): only hair is affected (for example, HR-gene atrichia).

   • Syndromic: hair loss plus other findings (teeth, nails, sweating, bones, immune system, or skin).

3. By skin changes

   • With papular lesions: tiny firm bumps form where follicles should be.

   • Without papules: smooth skin without bumps.

4. By scarring

   • Non-scarring atrichia: skin looks smooth; no scarring; follicles are absent or miniaturized.

   • Scarring atrichia: follicles are destroyed and replaced by scar tissue (less common for generalized forms, but can happen in severe inflammatory diseases).

Causes

1. Variants in the HR (hairless) gene
   A well-known cause of congenital atrichia. Babies may have fine hair at birth that falls out permanently. Many develop tiny follicular papules because follicles fail to mature.

2. Variants in the VDR gene (vitamin D receptor)
   Some children with vitamin D-dependent rickets type IIA have early, permanent hair loss because the receptor is needed for hair-cycle signaling.

3. Ectodermal dysplasias (group of genetic conditions)
   These conditions affect tissues from the “ectoderm” layer—hair, teeth, nails, sweat glands. Hair may be absent or very sparse across the body.

4. TP63-related syndromes (e.g., EEC spectrum)
   Variants in TP63 can disrupt development of hair, skin, nails, and teeth, causing widespread hair absence with other features like clefting or limb differences.

5. Netherton syndrome (SPINK5 variants)
   Mainly causes fragile hair and ichthyosis, but some people show extremely sparse scalp hair that can resemble generalized atrichia early in life.

6. Autoimmune alopecia universalis (severe alopecia areata)
   An acquired immune attack on hair follicles can cause complete scalp and body hair loss. It may begin later than congenital forms, but the end result can look similar.

7. Severe scarring scalp diseases (e.g., lichen planopilaris, discoid lupus)
   Widespread inflammation can destroy follicles. If extensive, hair loss can become generalized and permanent in the affected areas.

8. Chemotherapy-induced permanent alopecia (rare, dose-related)
   Most chemo hair loss regrows, but in rare cases high or specific agents cause long-lasting follicle damage and little regrowth.

9. Radiation exposure to the scalp
   High-dose radiation can permanently destroy follicles, leading to irreversible hair loss in exposed regions; if the field is large, loss appears generalized.

10. Severe tinea capitis with scarring
    Untreated deep fungal infections (kerion) can scar follicles and leave permanent patchy or extensive hair loss.

11. Congenital aplasia or hypoplasia of hair follicles
    Some babies are born with too few or poorly formed follicles across the scalp and body, leading to true atrichia.

12. Metabolic bone disorders with ectodermal features (e.g., rickets in some genetic forms)
    When gene pathways overlap between bone and hair biology, diffuse, early hair absence can occur.

13. Congenital hypothyroidism (rarely severe enough to mimic atrichia)
    Usually causes thinning rather than total absence, but in profound cases hair may be extremely sparse from infancy.

14. Severe malnutrition in early life
    Protein-energy deficiency can severely impair hair formation. Hair may be absent or very scant until nutrition is corrected.

15. Congenital infections (rare)
    Intrauterine infections can disturb skin and follicle development, leading to diffuse hair absence or sparse hair at birth.

16. Genetic defects in hair-shaft formation pathways
    Some shaft-fragility disorders lead to hair that breaks immediately on growth, simulating atrichia because hair never reaches visible length.

17. Autoimmune polyendocrine syndromes
    Combined endocrine autoimmunity can include alopecia universalis, with hair loss spreading to the whole body.

18. Severe chronic inflammatory skin disease in infancy
    Conditions with intense inflammation can disrupt follicle cycling and—if scarring occurs—produce lasting hair absence.

19. Iatrogenic scarring from neonatal procedures or burns
    Extensive scarring from medical devices, surgery, or burns can permanently erase follicles over large areas.

20. Unknown/idiopathic
    In a minority, careful testing does not find a definitive cause. The pattern is still consistent with lifelong, generalized hair absence.

Symptoms and signs

1. No scalp hair or hair that falls out in early infancy
   Parents often report normal or fine newborn hair that sheds and never returns.

2. Absent or very sparse eyebrows and eyelashes
   The eye area may look smooth. Lack of lashes can cause eye irritation from dust.

3. Little or no body, pubic, or axillary (underarm) hair
   Hair distribution across the body remains minimal through life.

4. Smooth scalp skin
   The scalp looks even and may lack visible hair pores (“follicular openings”).

5. Tiny firm bumps (papules) on the scalp or body
   In “atrichia with papular lesions,” small keratin-filled bumps appear where follicles failed to develop normally.

6. Normal scalp without inflammation
   Many nonscarring forms have no redness, scale, or pain; the skin simply lacks hair.

7. Dry skin or keratosis pilaris-like roughness
   Some people have dry, rough patches because follicles are abnormal or absent.

8. Photosensitivity or eye dryness (due to absent lashes/brows)
   Without lashes, eyes get dry or more light-sensitive.

9. Heat intolerance (in ectodermal dysplasia)
   If sweat glands are missing, the person may overheat easily.

10. Dental differences (syndromic cases)
    Conical teeth, delayed eruption, or missing teeth may accompany hair absence.

11. Nail changes (syndromic cases)
    Nails may be thin, brittle, or abnormally shaped.

12. Bone or growth issues (VDR-related rickets)
    Bowed legs or delayed growth can accompany hair loss in specific genetic forms.

13. Psychosocial stress
    Visible hair absence can affect self-esteem, school or work interactions, and quality of life.

14. No scarring or pain in most nonscarring forms
    Unlike scarring diseases, there is usually no tenderness or inflamed plaques.

15. Family history
    Others in the family may have been bald from infancy, suggesting hereditary cause.

Diagnostic tests

Physical examination

1. Full-body hair map
   The clinician checks scalp, eyebrows, eyelashes, beard/whiskers, and body hair. In generalized atrichia, hair is absent or extremely sparse everywhere, not just in patches.

2. Skin inspection for papules and follicular openings
   The doctor looks for tiny bumps and whether normal “pores” (follicular openings) are visible. Lack of openings suggests follicles are absent or scarred.

3. Nails, teeth, and sweat function clues
   Nail shape, tooth number, and ability to sweat are assessed to see if an ectodermal dysplasia or other syndrome is present.

4. Growth and bone signs
   Height, weight, and limb alignment are checked. Bowed legs or delayed growth point toward vitamin D receptor–related rickets.

5. Signs of inflammation or scarring
   Redness, scale, pustules, or shiny scarred skin suggest scarring diseases (like discoid lupus) rather than congenital atrichia.

Manual tests

6. Hair pull test
   The clinician gently tugs a small bundle of hair. In atrichia there may be no hair to pull, or the test shows absent active hair growth rather than active shedding as seen in telogen effluvium.

7. Hair tug/fragility test
   If any hairs are present, gentle stretching checks for shaft breakage. Immediate breakage suggests a shaft disorder; total absence favors atrichia.

8. Trichogram (hair-pluck microscopic exam)
   A few hairs (if present) are plucked and examined. In atrichia, anagen hairs may be scarce, and follicles may be miniaturized or absent, guiding the diagnosis.

9. Wash test / 60-second comb test
   Counting shed hairs after washing/combing helps distinguish active shedding disorders from a baseline state of little to no hair growth.

10. Eyebrow/eyelash traction check
    Gentle traction on lashes/brows (if present) assesses regrowth potential and rules out active inflammatory loss at the margins.

Laboratory & pathological tests

11. Scalp skin biopsy (histopathology)
    A tiny skin sample shows whether follicles are present. In congenital atrichia, follicles are absent or rudimentary, often with keratin-filled cysts in APL. This is the single most definitive test in many cases.

12. HR gene sequencing
    Finds variants in the hairless gene typical of hereditary atrichia. A positive result confirms the molecular cause and guides counseling.

13. VDR gene testing
    If rickets or bone signs are present, testing the vitamin D receptor gene can confirm the rickets-alopecia association.

14. Thyroid panel (TSH, free T4)
    Screens for hypothyroidism. It usually causes thinning, but severe early cases can mimic atrichia.

15. Iron studies (ferritin, iron, transferrin saturation)
    Low iron commonly causes diffuse shedding; normal results help point back to a congenital cause.

16. Calcium, phosphate, alkaline phosphatase, and 25-OH vitamin D
    Abnormalities support metabolic bone disease or VDR-pathway issues when clinical signs fit.

Electrodiagnostic tests

17. QSART (Quantitative Sudomotor Axon Reflex Test)
    Measures sweating after mild stimulation. Absent sweat supports an ectodermal dysplasia where hair, teeth, and sweat glands all form abnormally.

18. Pilocarpine iontophoresis sweat test
    A tiny electrical current drives pilocarpine into the skin to induce sweat. Very low sweat volumes suggest sweat-gland dysfunction, supporting syndromic diagnoses.

Imaging / optical tests

19. Trichoscopy (dermoscopy of scalp)
    A handheld video scope magnifies the scalp. In atrichia, clinicians often see no follicular openings, smooth skin, and sometimes tiny keratin plugs. It is painless and very helpful.

20. High-frequency skin ultrasound or reflectance confocal microscopy
    Noninvasive imaging can show the absence of normal follicles and help distinguish nonscarring vs scarring patterns without large biopsies.

Dietary molecular supplements

There is no supplement that regrows hair in generalized atrichia. Use only for general skin/eye health or specific deficiency, with clinician advice.

1. Vitamin D (e.g., 1000–2000 IU/day in adults; child dose per clinician)
   Function/Mechanism: Immune and skin barrier support; correct deficiency common in some regions.
   Note: Supplement only if low on blood test.

2. Omega-3 fatty acids (e.g., 1–2 g/day EPA+DHA in adults)
   Function: Anti-inflammatory; may reduce skin irritation and dryness.

3. Zinc (e.g., 10–15 mg elemental/day short course if low)
   Function: Helps wound healing and immunity when deficient.
   Caution: Excess zinc can lower copper.

4. Biotin (only if true deficiency, which is rare)
   Function: Keratin enzyme cofactor.
   Note: Routine high-dose biotin is not helpful and can distort lab tests.

5. Vitamin A (from food or multivitamin only)
   Function: Epidermal differentiation.
   Caution: Do not combine with oral retinoids; avoid overdose.

6. Vitamin E (dietary sources preferred)
   Function: Antioxidant; supports skin lipids.
   Caution: High-dose supplements thin blood.

7. Hyaluronic acid (oral or topical serums)
   Function: Hydration for skin/eyes (topical around eyes; oral data limited).

8. Lutein/zeaxanthin (per label)
   Function: Ocular surface and retinal antioxidant support for light exposure.

9. Collagen peptides (per label)
   Function: May modestly support skin hydration/elasticity; hair regrowth not expected.

10. Probiotics (per label; strain-specific)
    Function: May aid general skin comfort through gut-skin axis in some people; evidence variable.

Regenerative / stem-cell drugs

There are currently no approved “immunity booster,” regenerative, stem-cell, or gene-editing drugs that restore hair in generalized atrichia. Because follicles are permanently inactive from HR-gene biology, offering such drugs outside regulated clinical trials is unsafe and misleading. Here’s what to know and what to do instead:

1. Gene therapy for HR (research only)
   No human dosing exists. If a registered clinical trial appears in the future, enrollment would occur under strict protocols. Do not seek unregulated “gene therapy” clinics.

2. Autologous stem-cell injections / PRP marketed for congenital atrichia
   No evidence of benefit in this condition; avoid.

3. Mesenchymal stem-cell “IVs”
   Unproven and risky (infection, emboli). Avoid.

4. JAK inhibitors (oral/topical)
   Work for some alopecia areata (autoimmune), not for atrichia. Avoid for hair regrowth here.

5. Experimental follicle neogenesis labs
   Still basic science; no approved medical product.

6. Safe alternative focus
   Invest in cosmetic solutions (micropigmentation, microblading, prosthetics), skin/eye protection, and psychosocial support—these do improve daily life now.

Procedures/surgeries

1. Excision or curettage of symptomatic keratin cysts
   Procedure: Tiny incision or curette to remove the cyst contents; quick in clinic.
   Why: Relieves tenderness or repeated irritation/infection.

2. CO₂ laser ablation of multiple tiny cysts
   Procedure: Fractionated or focused CO₂ laser vaporizes superficial cysts; local anesthesia.
   Why: Treats many lesions efficiently with controlled healing. PMC

3. Scalp micropigmentation (medical tattooing)
   Procedure: Pigment dots placed in upper dermis to simulate hair stubble.
   Why: Long-lasting cosmetic coverage without a wig.

4. Eyebrow microblading / nanoblading
   Procedure: Semi-permanent pigment strokes to rebuild brows.
   Why: Restores facial framing; alternatives for those avoiding prosthetics. Byrdie

5. Selective laser, extraction, or cautery of milia-like lesions on the face
   Procedure: Pinpoint laser, manual extraction, or electrocautery by a dermatologist.
   Why: Cosmetic and comfort improvement; prevents picking/infection. VitalSkin Dermatology

Hair transplantation: Usually not helpful because follicles are absent/inactive broadly; donor sites are not available. Doctors rarely consider it, and only in atypical/mosaic situations.

Prevention tips

1. Daily SPF 50+ on all exposed skin (scalp, ears, neck).

2. Wear wide-brim hats/UPF clothing outside.

3. Use wrap-around glasses outdoors to protect eyes.

4. Keep artificial tears handy in windy, dusty, or air-conditioned places.

5. Avoid picking/squeezing papules; seek clinic removal instead.

6. Choose fragrance-free cleansers and moisturizers.

7. Wash bedding and hat liners regularly to reduce irritation/infection.

8. Use silk/satin pillowcases to lower friction.

9. Schedule regular dermatology checkups (6–12 months).

10. For families: seek genetic counseling when planning more children. orpha.net

When to see a doctor

• Right away / urgent: rapidly worsening redness, swelling, pus, fever; severe eye pain, light sensitivity, vision changes; severe skin reaction to a new cream.

• Soon (days–weeks): new tender clusters of papules; repeated infections; eyes feel gritty despite tears; any procedure complications.

• Routine: diagnosis confirmation, genetic counseling, building a long-term skin/eye care plan, and updates on new research.

---

What to eat, and what to avoid

• Eat: a varied diet rich in vegetables, fruits, legumes, whole grains, nuts, and lean proteins; sources of omega-3s (fish, flax, walnuts); water to stay hydrated (helps skin and eyes).

• Consider (if deficient): vitamin D and zinc under clinician guidance.

• Avoid: crash diets; high-dose vitamin A if you are on prescription retinoids; mega-doses of biotin (no benefit and can distort lab tests); harsh spices or heat on freshly treated skin; smoking (slows healing).

Frequently asked questions

1. Is generalized atrichia the same as alopecia universalis?
   No. Alopecia universalis is often autoimmune and sometimes responds to immune medicines. Generalized atrichia is genetic (HR gene) and is irreversible. PubMed

2. Can minoxidil or steroids help?
   No. They don’t restart hair in this condition.

3. Will hair transplant work?
   Usually no, because there aren’t working follicles to move or receive.

4. Can the bumps be removed?
   Yes. Dermatologists can extract or laser them when needed. PMC

5. Can this be cured with stem cells or gene therapy now?
   No approved cure exists yet. Avoid unproven clinics.

6. Is it inherited? What is the chance for the next child?
   It is usually autosomal recessive. If both parents carry the HR change, each pregnancy has a 25% chance of being affected. (A genetic counselor can confirm exact risks.) orpha.net

7. How is the diagnosis confirmed?
   By history, exam, and genetic testing of the HR gene. Dermoscopy often helps differentiate from alopecia areata. Lippincott Journals

8. At what age does hair fall out?
   Usually within the first months of life; eyebrows and lashes also go, and hair doesn’t return. PMC

9. Are the bumps dangerous?
   They’re usually benign keratin cysts. They can get irritated or infected if picked.

10. Can children swim and play sports?
    Yes, with sun protection, protective eyewear, and head coverings as needed.

11. What about school?
    Discuss hat/eyewear allowances and seating away from sun or drafts.
