I dyed my hair 2 months ago since then it had be falling out and dry how can I get my hair back
Make sure your hair gets a lot of moisture. Not sure which hair type you have but dying curls can really really really dry them out! You might want to deep condition at least 1 or 2 times a week if it's really weak. Do you use leave in conditioners as well?
Wash your hair less than you normally would, and use shampoo made for dyed hair. Get a good hair mask and follow all directions. Possibly next time you dye your hair, (if you do it again) try a different brand, and don't leave the mixture on your hair for as long. Hope it helps hun!
