In the past 2 years I've noticed my hair becoming thinner. I think this is due to stress and the decreased bloodflow (long story) in the right side of my head.
I am thinking of buying 1 or max 2 of the following 3 products:
-Spectral.F7 (Astressin-B)
-Spectral DNC-N (Nanoxidil)
-Revita shampoo
Since I'm a total beginner I've a question. Can any of these products have side effects on cognition and body? Like drowsiness, less energy or anything else?
Because any substance in oral supplements can have unwanted side effects, but is the same true for lotions and shampoo?
I don't know how these products work, but I am guessing that they are somehow absorbed by the skin or get in the bloodstream?
If I had to choose a maximum of 2 of the products mentioned above, which ones do you recommend?
PS: feel free to recommend other products.
