In July 22 I started losing my hair , my scalp was sore and I was prescribed harsh steroid creams, which didn’t work , by the November I had lost 50% . That’s when after trying so many other products I ordered the MD hair kit , and to my relief it started to grow back . After a year I was confident in my regrowth and went back to using my old shampoo. After one wash my scalp became dry and I recognised the painful sore feeling from the previous year, I went back to using restore shampoo and it immediately calmed my scalp - I think this is my shampoo for ever now.
