The most effective substances for eyebrow growth, according to dermatologist Marisa Garshick, are bimatoprost (found in Latisse) and minoxidil (found in Rogaine).
Understanding Eyebrow Growth
Eyebrow hair growth, like the hair on our scalp, follows a growth cycle. Understanding this cycle helps us appreciate why some methods are more effective than others.
- Anagen Phase (Growth Phase): This is when hair actively grows. The duration of this phase varies, and for eyebrows, it is relatively short.
- Catagen Phase (Transition Phase): This is a brief period where hair growth slows and the hair follicle shrinks.
- Telogen Phase (Resting Phase): Hair neither grows nor falls out during this phase. Eventually, it sheds, and the cycle restarts.
The Role of Bimatoprost and Minoxidil
According to a small-scale study, using bimatoprost and minoxidil may help increase hair density. Both substances work via different mechanisms:
- Bimatoprost: Primarily used to treat glaucoma, bimatoprost is believed to extend the growth (anagen) phase of the hair cycle. This results in longer, thicker, and darker hair.
- Minoxidil: A topical solution, minoxidil promotes hair growth by widening blood vessels and improving blood flow to the hair follicles. This can stimulate dormant follicles.
How to Use for Eyebrow Growth
Bimatoprost
- Application: Typically applied using a small applicator along the lash line, but it can also be carefully applied to the eyebrow area using a thin brush.
- Usage: Usually applied once daily.
- Caution: Avoid getting the product into your eyes. Possible side effects include skin darkening and irritation.
Minoxidil
- Application: Apply minoxidil liquid or foam directly onto the eyebrow area, ensuring complete coverage of the desired area.
- Usage: Usually applied twice daily.
- Caution: Like bimatoprost, avoid getting the product in your eyes. Minoxidil can cause scalp irritation in some people.
Other Considerations for Eyebrow Growth
While bimatoprost and minoxidil are effective, here are other tips to help promote healthy eyebrow growth:
- Diet: A balanced diet rich in vitamins and minerals, especially biotin, can support hair growth.
- Avoid Over-Plucking: Over-plucking damages hair follicles. Be gentle.
- Castor Oil: Some people find castor oil helpful. It is a moisturizing oil that may improve hair growth by keeping the eyebrow hair healthy.
- Proper Eyebrow Care: Clean eyebrows regularly to avoid blockages in the hair follicle.
- Stay Hydrated: Hydration is important for overall hair health.
Summary
| Substance | Active Ingredient | How it Works | Application |
|---|---|---|---|
| Latisse | Bimatoprost | Extends the growth phase of hair follicles | Once daily, carefully onto the brow area |
| Rogaine | Minoxidil | Widens blood vessels, improving blood flow to follicles | Twice daily, onto the brow area |
In summary, the best things to help with eyebrow growth are bimatoprost (found in Latisse) and minoxidil (found in Rogaine). Both of these are supported by the study and expert opinions. While other options like diet and castor oil are helpful in supporting healthy hair, bimatoprost and minoxidil are proven to be effective in increasing hair density.
