Keep your color natural.
Create a shield before sunning and swimming.
The most enjoyable things about summer—warm weather, time outdoors, exploring and swimming—can really take their toll on the hair. Before you indulge in summer fun, pre-soak your strands with fresh water, and slather it in a leave-in conditioning cream. Already soaked in pure, nourishing, protective things, hair will be less likely to absorb damaging elements like chlorine and salt.
Cleanse with care.
Avoid too much heat.
Summer is hot already. Your hair doesn’t need intense blow drying and hot tools on top of all that sun. The key is to limit your heat styling as much as possible. Try air drying most of the way, and only use styling irons occasionally. It’ll really minimize seasonal damage.

Lock in moisture.
Dry hair is summer’s biggest woe. You need all the moisture you can get. Which is no problem when you have a good solid routine of hydrating products—start with a good mask and leave-in conditioner. Also, when you go outside, try to wear a hat. It’ll keep the sun off your hair and preserve the moisture inside.
Stay healthy and hydrated.

Indulge in a night treatment.
The long, hot days of summer really do a number on your hair. Nighttime is a great opportunity to repair and restore its vitality. Apply a nourishing leave-in conditioning cream to hair before bed, concentrating on the dry, frizzy areas. By the time you wake up, your hair problems will have disappeared.
