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’?
