Dry, flaky & itchy scalp

Anyone experience dry, itchy and flaky scalp during pregnancy? I actually had this since Jun, been to doctors twice tried Dermasone & Ketanozole 2%(only tried once till I found out I am 5 weeks pregnant and don’t dare to continue) , bought other shampoos as well like Selsun blue(contains ammonia) & just started on Sebamed everyday shampoo but it doesn’t seem to get better. The 2nd pic was the amount of flakes on my pillow. I wash my hair everyday because it’s very itchy. I don’t know what I can use to relieve me, anyone had the same problem & resolved the issue? When I try to put fish oil the other day, my flakes became huge & yellowish I stopped.😖😩😭#advicepls #FTM
