What Causes Hair Loss?

Hair loss is a complex issue that can develop slowly or suddenly. Understanding the root cause helps determine the correct treatment plan. Here is a deeper breakdown:

1. Genetics & Hereditary Factors

Genetic hair thinning (androgenetic alopecia) is the most common cause.

• It gradually reduces hair density.

• The hair follicle becomes smaller over time.

• Growth phase becomes shorter, so hair appears thinner.
  This condition can start as early as late teens or early adulthood for some individuals.

2. Hormonal Changes

Hormonal fluctuations affect both men and women.
Common triggers include:

• Puberty

• Pregnancy & postpartum

• Birth control pills

• PCOS

• Thyroid imbalance

• Menopause
  When hormone levels shift, the hair cycle can move prematurely into a shedding phase.

3. Nutritional Deficiencies

Hair needs nourishment to grow strong. Lack of key nutrients such as:

• Iron

• Vitamin D

• Protein

• Zinc

• Omega-3
  can weaken follicles. Sometimes a blood test is required to confirm these deficiencies.

4. Scalp Health Problems

An unhealthy scalp can block hair growth.
Common scalp issues include:

• Build-up (product, oil, pollution)

• Dandruff / dryness

• Dermatitis

• Fungal imbalance

• Poor blood circulation
  These issues reduce oxygen, nutrients, and growth factors reaching the roots.

5. Stress & Lifestyle Factors

Stress increases cortisol levels, which directly affects the hair cycle.
Other lifestyle causes:

• Lack of sleep

• Crash dieting

• Smoking

• Excessive heat tools

• Chemical damage (bleaching, straightening)
  All of these weaken the hair shaft and follicle.

6. Medical Conditions

Certain conditions impact hair density:

• Autoimmune disorders

• Chronic illness

• Sudden weight loss
  Hair typically recovers, but professional guidance ensures faster improvement.

When should you worry?
If shedding continues for more than 2–3 months or you see visible scalp, it’s time for a proper scalp analysis.
