Post-Summer Hair: 6 Must-Have Masks, Serums & Oils

After months of sun, chlorine, and heat styling, your hair is ready for some serious love and care. A post-summer hair detox isn’t just about an in-salon treatment. It’s also about continuing to replenish what we just did at the salon, at home. To help you build a routine that works, we’re highlighting six of the most purchased and loved masks, oils, and serums from your favorites- Kérastase, Pureology, and Redken. Use them generously (or as often as your stylist recommends) and give your hair the nourishment it deserves!

1. Kérastase Elixir Ultime L’Huile Original Hair Oil (An industry favorite)

What it does:  A true icon in the hair world, this lightweight oil nourishes, smooths, and adds unbelievable shine.

Why people love it:  It never feels greasy and works on every hair type — from fine to thick. It’s also a stylist favorite for finishing a blowout.

When to use:  Apply to damp or dry hair, focusing on mid-lengths and ends. Perfect for fighting frizz and adding polish.

2. Kérastase Nutritive 8H Magic Night Serum

What it does: An overnight leave-in that delivers deep hydration while you sleep.

Why people love it: You literally wake up with softer, smoother, more

manageable hair. You cant call it beauty sleep without this essential.

When to use: Apply before bed to dry or damp hair (I know so convenient), comb through, and let it work its magic overnight.

3. Kérastase Genesis Fortifiant Scalp Serum

What it does: Targets fragile strands prone to breakage and helps reduce hair fall due to brushing.

Why people love it: It strengthens and smooths without weighing hair down. A game-changer for anyone with color-treated or stressed hair

 When to use: After cleansing, apply directly to the scalp and massage in. You have to stay consistent with this!

4. Redken Frizz Dismiss Mask

What it does: Deeply conditions frizz-prone, unruly hair, leaving it softer and more manageable.

Why people love it: It’s the go-to for taming summer frizz and rehydrating hair that’s been through humidity, chlorine, or sun.

When to use: Swap this in for your conditioner once a week, leaving it on 5–15 minutes before rinsing.

5. Redken Frizz Dismiss Instant Deflate Oil-In-Serum

What it does: A serum-oil hybrid that smooths flyaways, boosts shine, and protects against humidity. Hellooo Texas.

Why people love it: It works instantly — no crunch, no heaviness, just soft, frizz-free hair.

When to use: Use on damp hair before styling or apply lightly to dry hair to smooth and finish. ( I definitely prefer this one on dry hair right after styling)

6. Pureology Strength Cure Dream Healer Serum (NEW)

What it does: A repairing leave-in serum that mends split ends, strengthens weakened strands, and protects from heat up to 450°F.

Why people love it: It feels weightless but packs a powerful punch — repairing damage, restoring softness, and locking in shine. Plus, it’s 100% vegan.

 When to use: Really work this in your hands, the texture (and scent) changes with the heat in your palms. Apply to damp hair, mid-lengths to ends, before heat styling. You can also use it on dry hair to refresh and smooth.
