Any affordable scalp-repair shampoo/serum for sensitive scalp?
I'm seeking URLs leading to hopefully affordable products which are safe & effective. I've been researching the net, and could barely find info on this (rather just hair-repair or hair-loss). But not much info re: scalp-repair shampoo/serums for sensitive-scalp.
I'm nearing 60, and my scalp seems to have become sensitive from decades of brushing hair,
...as well as leaning back, while reading in bed.
Lately, when leaning back, it's like leaning on a black-and-blue mark.
I also believe my scalp became more sensitive after buying a supposedly "healthy" shampoo from an online health store, containing Argan oil. I'm not saying it was necessarily argan-oil or another ingredient as culprit, but after using it for awhile, my scalp became more sensitive.
Does anyone know of anything which can help me?
I know many of you may advise not to lean back while reading, but i'm really just seeking repair.
So again, any URLs to safe+effective products appreciated. Thanks.
