If you use a serum, do flat irons still dry out hair?

no, not as much...

if you dont put serum and flat iron your hair it will mess up REALLY BAD!!!! but if you put serum on before [maybe even after] you straighten your hair it will not damage a lot.

if you dont put serum it will maybe damage about 90% of your hair but if you DO put serum on then it will only damage maybe 10-15%

so good luck on on damaging your hair

p.s. you might still have split ends depending on how healthy your hair is currently

p.p.s. and if that doesnt work wich i garentee it will, you can by thermasilk or tresseme' or sunsilk shampoo it comes out really smooth and if you use sunsilk it will be easier to brush your hair. so once again hope it works out good for you :)

I think it depend on what kind of serum you use. I know when I was using Biosilk, it seemed to dry out my hair the more and more I used it. Then i started using Paul Mitchells Super Skinny, it worked a lot better. You need to find a serum with no alcohol, or with a lower percentage. Alcohol is what drys out your hair.
