What Causes Pubic Hair Loss

What Causes Pubic Hair Loss?

Pubic hair loss is often linked to aging and hormone changes, but it can also follow irritation from hair removal, skin conditions like eczema or psoriasis, infections, stress, nutrient deficiencies, medications, or autoimmune diseases such as alopecia areata. If hair loss is sudden, patchy, painful, or comes with sores or itching, a clinician can help identify the cause and treatment.

Understanding Pubic Hair Loss

Some people notice gradual thinning over years, while others experience sudden shedding or patchy loss. The pattern, timing, and any skin changes around the follicles usually offer clues. Because several conditions can look similar, identifying the trigger is the first step toward the right solution.

Common Causes Of Pubic Hair Loss

Aging And Natural Hormone Changes

Hair density can decrease across the body over time, including the pubic area. This is commonly related to lower levels of sex hormones and slower follicle cycling. Gradual, even thinning without redness or pain often fits this pattern.

Hormonal Imbalances

Hormones influence hair growth, thickness, and the length of the growth phase. Shifts or imbalances may cause noticeable thinning, especially when they happen quickly.

• Menopause or perimenopause (often linked to lower estrogen levels)
• Thyroid disorders (overactive or underactive thyroid)
• Polycystic ovary syndrome (PCOS)
• Postpartum hormone changes

Skin Conditions And Ongoing Irritation

Inflammation of the skin around follicles can weaken hairs and increase shedding. Scratching can worsen the cycle and lead to breakage or secondary infection.

• Eczema or contact dermatitis (often triggered by fragranced products, tight clothing, or pads)
• Psoriasis
• Folliculitis (inflamed hair follicles)

Autoimmune And Other Medical Conditions

Some medical conditions affect follicle function or blood flow, which may show up as thinning or patchy loss.

• Alopecia areata (an autoimmune condition that can affect any hair-bearing area)
• Diabetes and circulation-related issues
• Nutrient malabsorption conditions that contribute to deficiencies

Infections, Including Sexually Transmitted Infections

Infections can inflame the skin and damage follicles, leading to shedding. Treatment depends on the specific cause, so proper diagnosis matters.

• Fungal infections (such as tinea/ringworm)
• Bacterial infections
• Certain STIs can be associated with hair loss, especially when symptoms are systemic

Stress, Rapid Weight Changes, And Poor Nutrition

Major stress, illness, surgery, or rapid weight loss can push more follicles into a resting phase, leading to shedding weeks later. Diet also matters because follicles rely on a steady supply of nutrients.

• High stress or a traumatic event (telogen effluvium)
• Low iron, zinc, or vitamin D
• Very low-calorie diets or restrictive eating patterns

Medications And Medical Treatments

Some drugs and treatments can trigger shedding as a side effect. If timing lines up with a new prescription, do not stop medication on your own—ask your clinician about alternatives.

• Chemotherapy and certain cancer treatments
• Some antidepressants
• Hormonal therapies or changes in contraception

Hair Removal, Friction, And Mechanical Damage

Frequent shaving, waxing, or aggressive exfoliation can irritate the skin and inflame follicles. Tight clothing and repetitive friction may also contribute. If irritation is chronic, follicles can struggle to produce strong hair.

Symptoms That Matter

Pubic hair loss is not always a stand-alone issue. These signs can point to an underlying condition that needs treatment:

• Itching, burning, or persistent redness
• Painful bumps, pus, or crusting around follicles
• Scaly patches, thickened skin, or bleeding with scratching
• Patchy bald spots or sudden, rapid shedding
• Sores, blisters, or unusual discharge

How Pubic Hair Loss Is Diagnosed

A clinician may ask about your timeline, hair removal habits, stressors, medications, and recent illness. A skin exam can reveal inflammation, infection, or scarring. Depending on the findings, they may recommend blood tests to check thyroid function and nutrient levels, or take a small skin sample for confirmation in complex cases.

Solutions And Treatment Options

Treat The Root Cause

The most effective approach depends on what is driving the hair loss.

• For infections: targeted antifungal or antibacterial treatment
• For dermatitis or eczema: removing triggers and using appropriate topical therapy
• For hormone-related shedding: medical evaluation and treatment options tailored to your situation
• For autoimmune causes: a dermatologist can discuss evidence-based therapies

Support Healthy Regrowth

Once the cause is addressed, regrowth may take time because follicles cycle slowly. Gentle care helps protect the area while it recovers.

• Use mild, fragrance-free cleansers and avoid harsh scrubs
• Pause waxing and reduce close shaving if irritation is present
• Choose breathable underwear and avoid tight clothing during flare-ups
• Prioritize protein intake and correct proven deficiencies under medical guidance

When Hair May Not Fully Return

If there is scarring, repeated deep infection, or long-term inflammatory disease, follicles can be permanently damaged. Early assessment helps reduce that risk.

When To Seek Medical Advice

Arrange medical evaluation if pubic hair loss is sudden, patchy, or worsening, or if you notice skin changes. Seek urgent care if you have severe pain, spreading redness, fever, or rapidly enlarging sores.
