Have been using this product for 3 weeks but haven’t noticed any result

I have used Invati before am still undecided as to whether it does thicken hair. I think it has improved slightly, but I think you would have to use the whole system for six months or so to get real results. Also, a trichologist would tell you there isn't anything that could really make a big difference, or men wouldn't go bald!
The main reason for my purchase is that it actually helps a lot with my sensitive scalp, which can become itchy.

Would buy this just for the smell, I keep forgetting to apply this so unsure on the difference

Excellent product. Recommended by my hairdresser and she was right. It works wonders
