17. Properly Hydrate Your Hair
Maturing hair can split more easily and start to thin, which means you have to put special focus on not only hydrating your hair, but trying not to dry it out. Try to only shampoo every second or third day so as not to strip the natural oils from your scalp, use gentle shampoos and conditioners, and invest in sulfate-free products. Also try to avoid hot showers, since that can dry the skin and strip oils.
