When temperatures climb and the sun beats down, summer becomes one of the harshest seasons for your hair. UV exposure, humidity, and heat styling can strip your strands of moisture, leaving hair dry, frizzy, and vulnerable to breakage. Increased sun exposure, frequent washing, chlorine, and saltwater all take a toll. This happens because the cuticle (your hair’s protective outer layer) is compromised, allowing moisture to escape and external stressors to enter. A top-tier heat protectant should do more than just shield from heat-it should treat your hair at the same time. This is where Kérastase’s Thermique range shines.
1. If your curls feel dehydrated or frizzy-especially during summer humidity-Nectar Thermique is your go-to. This anti-frizz blow-dry milk is ideal for medium to thick dry hair.
2. Been overdoing it with color, bleach, or heat styling? Ciment Thermique is a heat-protecting, strengthening cream designed to fortify fragile hair. Summer hair care is about protection and prevention. Don’t let the season leave your strands brittle and fried.
What makes a great heat protectant for summer hair
A top-tier product should form a protective barrier over the cuticle, minimize moisture loss, and offer conditioning benefits to keep hair manageable in humidity and sun exposure. Hydration retention, UV protection, and heat defense all in one formula help prevent frizz, split ends, and color fade. In hot weather, lightweight textures that won’t weigh hair down are especially valuable, along with ingredients that seal the cuticle and smooth strands for a sleek, healthy look.
Overview of Kerastase Thermique options
- Nectar Thermique - anti-frizz blow-dry milk for medium to thick dry hair; excellent for dehydrated curls and humidity.
- Ciment Thermique - heat-protecting, strengthening cream for fragile or chemically treated hair; fortifies and seals the cuticle.
Both products are designed to combine heat protection with treating benefits, aligning with the needs of summer hair care: shielding from heat while addressing moisture loss, damage, and maintenance of color.
How to use Kerastase Thermique effectively
- Apply a small amount to towel-dried hair, focusing on mid-lengths and ends.
- Distribute evenly with a comb or fingers before styling or blow-drying.
- Style as usual; use heat tools at appropriate temperatures to minimize damage.
For best results in hot, humid conditions, pair a heat protectant with a lightweight leave-in conditioner and regular UV protection spray or cream to reduce sun-induced damage and maintain moisture balance.

Practical tips for summer hair care
- Limit washing frequency to prevent stripping natural oils; use a clarifying wash periodically to remove product buildup.
- Rinse with cool water at the end of washing to help seal the cuticle.
- Protect hair from chlorine and saltwater with a pre-swim leave-in conditioner or barrier spray.
- Choose styling techniques that minimize heat exposure when possible; air-dry segments of the hair as needed.
