I HAVE dry and rough hair with split ends. Sometimes I have to be exposed under the hot sun for a few hours for outdoor activities. I suspect this is partly the reason why my hair breaks and falls easily. But I do apply hair serum every day. I’ve tried various hair treatments but nothing seems to help. Can you suggest which hair products to use? – Yi Fei
Anderson Cheah, Kerastase educator, says that your rough, dry hair and split ends may be due to your scalp condition. If your hair is naturally dry, it’s because the sebaceous glands aren’t producing enough sebum, which means that your scalp and hair are not protected and supple.
