I have been using this product for over a year and it's one of my favorite serums! This is my second bottle and the ingredients alone are worth it.
Key ingredients:
Copper Tripeptide-1
Caffeine
Tea Tree Oil
Amino Acids
Hyaluronic Acid
It's a lightweight formula that doesn't leave your hair greasy. Because of the menthol & peppermint oil in it, it gives a slight tingle sensation (my favorite part) and feels nice on the scalp. It also helps with product build up, and so far I haven't had any problems with shampoo residue hanging out on my hair so I feel it's working in that regard.
Comes in a 50ml and 100ml bottle and you can subscribe on the site to save money! I also like that the bottle has a window on the side so you know when you're close to running out.
I haven't really noticed a difference hair growth wise, but I also don't use it very frequently, so I need to get better at that. If you use consistently for 90 days you'd see better results per their site! The price is also a little high ($48) so it makes it hard to consistently purchase
