- Ita M.Verified BuyerI recommend this productRated 5 out of 5 stars1 week agoAmazing!
I love that I can use this in my hair every day without it feeling greasy, something I’ve always struggled to find, especially with my finer hair. I’ve been using it for around four weeks now, and I’m already starting to notice new baby hairs, particularly around my hairline. I’m really excited to see how my hair continues to improve with ongoing use.

I've been using this product every single day for almost 2 months, and I am definitely starting to see baby hairs grow back in an area where I'd lost some hair along my hairline. Definitely recommend & will be repurchasing!

I have been using this product on and off as I keep forgetting to use it, it does feel nice it isn’t greasy or smelly which is good as I have thin hair and wouldn’t like anything to make me need to wash it due to product being seen, I haven’t noticed any difference as yet but I haven’t been using it consistently but will continue on
