Brow growth serum


I am a facialist and brow specialist. I currently do 'brow perming' and want to offer a conditioning serum to my clients that helps the brows stay soft (as the perming lotion dries the hairs) but also to stimulate hair growth so clients have more brow hairs.

I have seen studies that show peppermint oil had better hair growth rates than minoxidil. In the study the peppermint oil was 3%. 

I feel that this would be extremely high for a serum that went on the brow area. Would it still be effective at lower levels?

I think essential oils max level for leave on is 1%. Would this still be effective? I think that even this may be too high as it is so close to the eye.

I would have mixed with some humectants. I know that people use castor oil on their eyebrows and I think the ricinoleic acid is why it 'works' but it is just 'claims'?

Thank you.

    You can't believe every study published. Peppermint oil does not work better than minoxidil.  No, castor oil does not make eyebrows grow either. It's a myth that many people believe.

    In reality, there is no non-drug compounds that you can add that will make hair grow. Using essential oils at a high level around the eyes is not a good idea.

    My advice is that you stick with the conditioning serum and stay away from making any hair growth claims.
