Frequently Asked Questions

Is eyebrow serum safe to use?

Most of the eyebrow serums and gels are safe to use. However, if you are allergic to any specific ingredient and are skeptical about buying a serum, check the list of ingredients and make sure that you are not allergic to any of these ingredients. Also, there are some serums and gels that are approved by the FDA or ophthalmologists or dermatologists.

When can I expect to see results?

Most of the eyebrow growth serums offer results within 4-6 weeks of use. However, the natural growth cycle of eyebrows is three months, and for eyelashes, it is two months, so it is better to use the brow growth serum for 3-4 months for best results. Even after you achieve the results, use the brow enhancing gels to maintain the growth and thickness of your eyebrows. Use the serum once or twice a day as recommended.

What happens when I stop using eyebrow serum?

When you stop using the eyebrow serum, it doesn’t get enough nourishment and hydration that the serum used to provide it. So after you stop using the serum, your brows might get scanty and thinner again. It is recommended to keep using the eyebrow serum for maintaining the thickness of your brows.

Can I use eyelash serum to grow my eyebrows?

Several serums are designed for both brows and lashes. However, while applying the serum to your lashes, it is vital to apply the serum with utmost caution because you can drop it in your eyes. If you want to use a serum for brows and lashes, choose a natural and chemical-free serum to prevent any discomfort.

Can you use eyebrow serum every day?

Yes, using eyebrow serum daily will result in rapid eyebrow hair growth. It will also keep your eyebrow hair healthy and moisturized.

Can a lash serum help your eyebrows grow?

Yes, lash serum can help to grow eyebrows, as they often have ingredients similar to brow serums.

Can you regrow eyebrows after 50 using eyebrow growth serum?

Yes, eyebrows can regrow even after 50. Use an eyebrow growth serum with keratin and protein that naturally stimulates brow development.
