We know that smoking can be harmful for our health, as it can lead to numerous issues, such as respiratory issues and cancer. However, smoking can also cause hair loss in the long run. Tap to know how!

Hormonal Imbalance

Smoking cigarettes can affect hormone levels, especially DHT (Dihydrotestosterone), which when increased can shrink hair follicles.

Dandruff

Smoking can cause the body and scalp to dehydrate, leading to irritation, dryness, and dandruff.

Reduced Blood Flow

Cigarettes can reduce blood flow to the scalp by constricting the blood vessels, which weakens hair follicles and leads to hair loss.

Hair Ageing

Smoking leads to premature greying of the hair and makes them thin and brittle due to cell damage and impaired scalp health.

Reduces Collagen Production

Smoking impairs the cells ability to produce collagen, weakening the scalp and inhibiting hair growth.
