Huma - I dyed my hair like a million times through the years....from like age 16- 22 it was NEVER my natural hair color. I think the most extreme thing I did was dye it 10 times in a six month time period.
mashAllah my hair never became dry or fall out. My hair is almost down to my waist and It's the thing that I get the most compliments on. Very thick and shiny. People warned me that it would fall out due to damage but it never happened. However, I will note that I have always been very conscientious of taking care of my hair health (before dying it, during the years I dyed it and even now) .... weekly hot coconut oil/olive oil treatments, only washing it every 2-3 days as opposed to everyday, and always taking a multivitamin.
woww! Having healthy, thick and shiny hair is one of my dreams! (The other one is to have a clear skin!) I know oil treatments help soo much but the thing I find hard in the busy life is to stick to these treatments regularly. I would do it a couple of times and then forget about it for the next month!
Also, which multivitamins do u take?
