Summer Hair Tips for Straight, Wavy, and Curly Hair

July 11, 2026

Summer is beautiful, but it's not always kind to your hair. Between the UV exposure, humidity, chlorine, and saltwater, your strands take a beating from June through August. The good news? A few targeted adjustments to your routine can make all the difference, no matter your hair type.

Straight Hair: Fighting Flatness and Frizz

Straight hair tends to show oil and humidity effects quickly. In summer, you might notice your hair going limp faster or picking up frizz along the hairline.

Clarify regularly. Sweat, sunscreen, and product buildup accumulate faster in summer. Use a clarifying shampoo once every 1 to 2 weeks to reset your scalp.
Go lighter with products. Heavy creams can weigh straight hair down. Opt for a lightweight leave-in conditioner that adds moisture without sacrificing volume.
Protect before you swim. Wet your hair with clean water before entering a pool or the ocean. Saturated hair absorbs less chlorine and salt.
Use UV protection. Look for products with UV filters or wear a hat to prevent colour fading and dryness from sun exposure.

Wavy Hair: Enhancing Definition Without the Frizz

Wavy hair sits in a sweet spot between straight and curly, which means it can go either way depending on humidity. Summer often pushes it toward frizz rather than definition.

Embrace the plop method. After washing, use a microfiber towel or t-shirt to scrunch and plop your waves into shape before air drying. This encourages definition and reduces frizz.
Apply leave-in on soaking wet hair. The wetter your hair when you apply product, the better your waves will clump and define. THICK Leave-In works beautifully on damp wavy hair, adding moisture and helping waves form without crunch.
Avoid touching your hair while it dries. Touching disrupts the wave pattern and introduces frizz. Let it set completely before scrunching out any cast.
Refresh mid-week with water and a small amount of leave-in rather than re-washing, which can strip natural oils your waves need.

Curly and Coily Hair: Sealing in Moisture All Season Long

Curly and coily textures are the most vulnerable to summer dryness. The combination of heat, humidity fluctuations, and UV exposure can leave curls feeling parched and undefined.

Deep condition weekly. Summer calls for more intensive moisture treatments. A weekly deep conditioning session helps replenish what the sun and heat strip away.
Layer your products intentionally. Start with a leave-in conditioner on soaking wet hair, then seal with a cream or oil to lock moisture in. This LOC (Liquid, Oil, Cream) or LCO method is especially effective in summer.
Protect your curls at night. Use a satin or silk pillowcase or wrap your hair in a satin scarf to prevent friction and moisture loss overnight.
Rinse after swimming. Always rinse chlorine and salt out of your hair immediately after swimming, then reapply your leave-in to restore moisture.
Protective styles are your friend. Braids, twists, and buns reduce daily manipulation and protect your ends from environmental damage during peak summer months.

Universal Summer Hair Rules

Regardless of your texture, these habits apply across the board:

Stay hydrated. Hair health starts from within.
Trim your ends before summer to remove any existing damage before it worsens.
Minimize heat styling. Let summer's warmth do the work and air dry whenever possible.
Always apply a leave-in conditioner after washing. It's the non-negotiable step that bridges the gap between clean hair and styled, protected hair.

Summer doesn't have to mean sacrificing your hair's health. With the right routine tailored to your texture, you can enjoy the season and come out the other side with strong, hydrated, beautiful hair.
