Thanks to the weather and the festivities, many of us have hair that’s weakened and damaged, having been teased, sprayed, pulled, blow-dried, straightened, curled and then rained on for weeks and weeks. If you dye your hair (and who doesn’t?) Olaplex, details below, is an impressively effective repair treatment that you can have in salon, mixed in with the colourant, and there’s a take home version to use pre and between dyeing. Also consider oils to leave in your hair overnight. You can buy them but try olive or coconut oil as a cheap alternative from your own kitchen (you might like to wear a shower cap if you like your pillows).
