my hair is extremely damage from heat products so is it important to trim the split ends ?
i just wanna ask is it other ways except cut the split ends like hair mask or something ?
cut them !! Even if it means your hair will be short. You can use as many treatments as you want but there's no point to it if you don't get rid of the real damage first. I had split ends in high school almost up to my scalp ( I straightened it everyday). After I cut it, it was so short but it's the best thing I did for my hair. Your hair will thank you later lol
