Using heated hair tools like blow dryers, flat irons and curling irons can damage your hair quite a lot. To combat this, use a shampoo and/or conditioner that contains reparative proteins. You should also a) start doing deep conditioning treatments weekly, and b) always be sure to use a heat protectant.

Washing your hair too often can strip your hair of its natural oils, which can dry it out faster. Instead, try washing your hair less often — and when you do, don't shampoo more than once. We also recommend looking at what's in your shampoo to see if it contains sulfates or parabens that can further dry out your hair.

Your hair loses moisture when it's shampooed, so it's important to replenish it with a good conditioner. If you use a lot of heat styling products, or have your hair colored regularly, then you also need to make sure you get a great regular conditioner (as well as a deep conditioner) to really hydrate your hair.To this end, we've really been loving the adorable Briogeo Don't Despair, Repair Honey Moisture Deep Conditioning Mask, $36.

The longer you wait between getting your hair touched up, the better. The ammonia in hair dye dries out your hair and too-frequent touch-ups will really do a number on your tresses. So, experiment with ombre styles and stock up on color-preserving hair products!
