Hair Fall: Causes, Biotin and Collagen Explained

Losing 50 to 100 hairs a day is normal. When you notice thinning, a wider parting or clumps in the shower, it is worth looking at the cause.

Common causes of hair fall

  • DHT sensitivity: a hormone that can shrink hair follicles over time, common in pattern hair loss.
  • Nutrient gaps: low protein, iron, biotin, zinc or vitamin D.
  • Stress: a stressful period can push many hairs into the shedding phase.
  • Thyroid imbalance and hormonal changes, including after pregnancy.

Where biotin helps

Biotin (vitamin B7) supports keratin, the protein your hair and nails are made of. It is most useful when your diet falls short.

Why collagen matters

Marine collagen peptides provide amino acids that support skin elasticity and the structure around hair follicles. Many people take it for skin, hair and nails together.

A complete approach

Eat enough protein, manage stress, be gentle with heat styling, and support your hair from within. Keoraveda Grow & Shine combines biotin, marine collagen and a DHT-blocker matrix in one capsule. For skin and nail structure, Sephelemo Premium is another option.

Sudden or patchy hair loss should be checked by a dermatologist.
