Yes, retinol can affect hair, primarily by promoting hair growth. Research indicates that it positively impacts hair follicles.
How Retinol Affects Hair Growth
Retinol, a derivative of vitamin A, influences hair growth through several mechanisms:
- Prolonging the Anagen Phase: According to research (2), retinol increases the rate of hair growth by extending the anagen phase, which is the active growth phase of the hair cycle. A longer anagen phase means hair follicles spend more time growing, resulting in longer hair.
- Vellus to Terminal Hair Conversion: Retinol plays a role in converting vellus hairs (fine, short "baby hairs") into terminal hairs (thicker, longer, pigmented hairs).
- Enhancing Other Hair Growth Solutions: Retinol works in conjunction with other hair growth treatments to produce denser hair regrowth (2).
Here's a table summarizing retinol's effects on hair:
| Effect | Description |
|---|---|
| Increased Growth Rate | By prolonging the anagen phase of the hair cycle. |
| Hair Conversion | Converts vellus hairs (baby hairs) to terminal hairs (thicker, mature hairs). |
| Enhanced Regrowth | Works with other treatments to promote denser hair regrowth. |
Practical Implications
Incorporating retinol into your hair care routine, potentially alongside other hair growth products, might contribute to healthier and fuller-looking hair.
