It happened to me also
I used an exellent shampoo and lotion name : sorciere ( take the black bottle with red writting)
use the shampoo every time you wash your hair and try to wash it only 1 or 2 times a week not more because of the bad water and if you can use in the begining the miniral water ( nestle or rayyan...) and buy also sorciere (lotion ) also the black bottle not green because there are many colors you can use this evey day without washing your hair.
it's exellent , i use it and in just few days my hair stoped falling and the hair start growing in the emty places.
I think the shampoo is 140Qr and lotion is 45Qr
you can find it in the pharmacy of the centre near Ramada signal next to basket robbins.
I recommend sorciere to many of my friends and they are very happy.
it's from japan and made from garlic means natural.
good luck
