How to protect your hair from heat: 5 tips

You wear SPF on your face (and maybe even your hands, neck, and scalp), but your hair? It’s often left to fend for itself. Sun exposure can dry it out, fade your colour, and rough up the cuticle. It's basically a sunburn for your strands. If your hair feels brittle by July, this might be why.

Here’s how to keep it protected all summer long.

1. Wear a hat (seriously): it sounds obvious, but covering up is the most effective (and easiest) way to shield your hair from UV damage. A hat isn’t just a style choice. I’s a physical barrier that blocks direct sunlight and prevents moisture loss.

2. Use leave-in conditioner: don’t skip it. Leave-ins help lock in moisture, add a bit of weight to protect strands from drying out, and act like sunscreen for your hair. Look for formulas with UV filters or hydrating ingredients like aloe or glycerin.

3. Pre-treat before outdoor days: if you’re heading to the beach, pool, or on a long hike, give your hair a little prep. Wet it first, then apply a hydrating product. This creates a buffer that helps keep your strands from absorbing too much salt, sun, or chlorine.

4. Go easy on the shampoo: washing too often strips your hair’s natural oils, which are your first line of defence against dryness. Try spacing out wash days and using a co-wash or just rinsing with water when possible.

5. Replenish after sun exposure: just like your skin, your hair needs care after sun time. Use nourishing masks or deep conditioners once or twice a week to restore moisture and strength. Look for ingredients like shea butter, coconut oil, or keratin.
