How does the hair loss product Regaine work?

Regaine, also known by its generic name minoxidil, is a topical treatment used to promote hair growth and prevent further hair loss. Here's how Regaine works:

1. Vasodilation: Minoxidil is a vasodilator, which means it causes the blood vessels to widen. This allows more blood, oxygen, and nutrients to reach the hair follicles. Improved blood flow can stimulate the follicles and promote hair growth.

2. Prolonging the Anagen Phase: The hair growth cycle consists of three phases: anagen (active growth), catagen (transition), and telogen (resting). Minoxidil helps extend the anagen phase and reduce the duration of the telogen phase, leading to longer and thicker hair growth.

3. Increasing Hair Follicle Size: Regaine can enlarge the size of hair follicles, resulting in thicker and more robust hair shafts. This can help improve the overall appearance and density of the hair.

4. Anti-inflammatory Effects: Minoxidil may have some anti-inflammatory properties that help reduce inflammation in the scalp. Inflammation can contribute to hair loss, so reducing it can create a more favorable environment for hair growth.

Regaine is typically applied directly to the scalp twice daily and can be used by men to treat androgenetic alopecia (male-pattern baldness) and by women to treat female-pattern hair loss. It's important to follow the recommended dosage and instructions for use as prescribed by a healthcare professional to achieve optimal results.
