1

Genetics

(DHT Sensitivity)

Family history and inherited DHT sensitivity can shrink follicles and gradually shorten the hair growth cycle.
2

Hormonal
Changes

Pregnancy, menopause, thyroid imbalance, and androgen changes can trigger temporary or progressive shedding.
3

Nutritional
Deficiencies

Low iron, vitamin D, protein, zinc, or B vitamins may affect follicle strength and healthy hair production.
4

Stress & Telogen
Effluvium

Physical or emotional stress can push more follicles into the resting phase, causing increased shedding.
5

Scalp
Conditions

Inflammation, dandruff, psoriasis, infections, and other scalp conditions can weaken follicles or disrupt growth.
6

Medications

Certain blood thinners, antidepressants, chemotherapy agents, and hormonal medications list hair loss as a side effect.

Types of Alopecia

Not all hair loss is the same. Understanding your type helps determine the right treatment.

Androgenetic Alopecia(AGA)

Androgenetic Alopecia(AGA)

Gradual thinning around the hairline or crown linked to inherited follicle sensitivity.

Telogen Effluvium

Telogen Effluvium

Temporary shedding that can follow stress, illness, surgery, childbirth, or nutritional changes.

Alopecia Areata

Alopecia Areata

Patchy hair loss caused when the immune system affects active hair follicles.

Traction Alopecia

Traction Alopecia

Hair thinning, broken hairs, redness, itching, bumps, soreness, hairline recession

Scarring Alopecias

Scarring Alopecias

Inflammation can permanently damage follicles and replace healthy tissue with scar tissue.

Myths Debunked

Let’s separate fact from fiction.

This is a common misconception. Androgenetic alopecia (AGA) is the most common cause of non-scarring hair loss worldwide, and early-onset AGA frequently begins during the second or third decade of life not just in older men. Both men and women can experience hair loss at any age, with up to 80% of men developing some degree of AGA during their lifetime, and 40–50% of women experiencing female pattern hair loss by age 70.

No. Hats do not cause androgenetic alopecia. Hair loss is driven by the interaction of genetic predisposition, androgen sensitivity, and follicular microenvironment alterations not external pressure or friction from headwear. However, tight headwear worn continuously might contribute to mechanical traction alopecia, which is a separate condition.

DHT blockers can help stabilize progression in some patients, but AGA is multifactorial and progressive. Androgenetic alopecia results from genetic predisposition, androgen sensitivity, follicular miniaturization, microinflammation, and stem cell dysfunction not DHT alone. Regenerative approaches like AMT counteract DHT-driven mechanisms and support the follicular microenvironment, offering a broader therapeutic strategy beyond pharmacological intervention alone.

Hair loss genetics are more complex. AGA is a polygenic disease individuals inherit increased follicular sensitivity to androgens from both parents, not just the maternal side. Genetic predisposition involves multiple inherited factors across your family history, not a single line of inheritance.

No. Normal hair washing does not cause AGA. The natural shedding of 50–100 hairs per day during the exogen (shedding) phase is normal and healthy. Washing frequency does not trigger or worsen androgenetic alopecia.

When to See a Doctor

Don't wait until hair loss is advanced. Early intervention produces better outcomes.

Find a Certified Specialist

Early

Early changes can be subtle:

  • More hair shedding than usual
  • Slight thinning around the hairline
  • Wider parting or reduced volume

Seeing a specialist early helps identify the cause, protect active follicles, and create a plan before hair loss becomes more visible.

Early

Moderate

Hair loss is becoming more visible:

  • Noticeable receding hairline
  • Reduced density in crown area
  • Slower regrowth

As these signs progress, hair loss can start to affect overall appearance and confidence. A receding hairline, thinning at the crown, and slower regrowth often indicate that hair follicles are weakening and need timely attention to prevent further loss and restore healthier growth.

Moderate

Advanced

Hair loss is extensive or progressing quickly:

  • Larger bald or thinning areas
  • Scalp visibility across multiple zones
  • Little response to routine care

Advanced hair loss needs medical evaluation to understand follicle activity, rule out underlying causes, and determine which treatment options are still suitable.
