Caffeine shampoo aims to stimulate hair growth primarily by blocking DHT (a hormone linked to hair loss) and improving scalp circulation.
Here's a more detailed breakdown:
-
Blocks DHT (Dihydrotestosterone):
- DHT is a hormone known to contribute to androgenetic alopecia, also known as male or female pattern baldness.
- Caffeine may help block the effects of DHT on hair follicles. This can help prevent the miniaturization of hair follicles, a key characteristic of androgenetic alopecia, and potentially encourage hair growth.
- This DHT-blocking action can help unclog hair follicles and potentially rejuvenate dormant ones.
-
Improves Scalp Circulation:
- Caffeine can stimulate blood flow to the scalp.
- Increased blood circulation ensures that hair follicles receive more nutrients and oxygen, which are essential for healthy hair growth and follicle health.
- Improved circulation can revitalize hair follicles and potentially extend the anagen (growth) phase of the hair cycle.
-
Stimulates Hair Growth:
- By targeting DHT and improving circulation, caffeine shampoo aims to provide a more favorable environment for hair growth.
- Consistent use is typically required to see noticeable results.
- The effectiveness can vary depending on individual factors and the specific formulation of the shampoo.
In summary, caffeine shampoo works by counteracting the effects of DHT and boosting blood supply to the scalp, theoretically encouraging healthier hair follicles and stimulating growth.
