I have had it for 4 days. I am new to reddit, this is my first time posting here. I was told by the girl at the store that she thought i might be having some sort of eczema or psoriasis on my scalp areas because they were so scaly and red. She said she has heard of people getting it from using shampoos with harsh ingredients like SLS which strips your skin and makes you super dry and susceptible to things like dandruff and psoriasis, but i haven’t used anything else than shampoo in a long time so I don’t really know how much to trust what she said since its just her opinion. So if anyone can help me out with something before i go see someone who specializes in this problem that would be great!
