Why Your Hair Gets Lighter and Frizzier in the Summer – and What You Can Do About It

Summer’s here — and your hair knows it.

At our Japanese hair salon in Brooklyn, we hear this all the time:

“My hair feels different lately. It’s lighter… and kind of frizzy.”

If that sounds like you, you’re not imagining it. Summer heat, sun, humidity, and water exposure can totally change the way your hair looks and feels. Whether you’re going lighter unintentionally or constantly battling frizz, here’s what’s going on—and how to fix it.

☀️ Why Does Hair Get Lighter in Summer?

The biggest culprit? UV rays.

Sunlight breaks down melanin, the pigment that gives your hair its natural color. This process, called oxidation, causes your hair to lighten over time. It’s basically like nature’s bleach—and once that pigment is gone, it’s not coming back (at least not until your hair grows out).

Other factors that make summer lightening worse:

• Chlorine and saltwater open the cuticle, making hair more porous and vulnerable.

• Heat and humidity accelerate the breakdown of melanin.

• Long sun exposure fades both natural and dyed hair faster than usual.

🧢 How to Prevent Summer Hair Fading

Want to keep your color rich and vibrant all season? Here’s how:

• Use UV-protective hair products

  Look for sprays or leave-ins with built-in sun protection.

• Wear a hat

  A wide-brimmed or bucket hat isn’t just stylish—it’s smart.

• Rinse after swimming

  Always rinse your hair with clean water after a dip in the pool or ocean.

• Deep condition once a week

  Hydrated hair is less likely to fade or become brittle.

🌬 Why Does Hair Texture Change in the Summer?

If your hair feels frizzier, drier, or flatter than usual, it’s not just in your head—it’s in the air.

Here’s what summer does to your hair:

• Humidity causes swelling

  Your hair absorbs moisture from the air, making it puff up and frizz.

• Sun exposure zaps moisture

  UV rays dry out the outer layer of your hair, leaving it dull and fragile.

• Sweat, salt, and city grime

  All that environmental buildup strips moisture and can make your scalp feel greasy while your ends feel dry.

💧 How to Prevent and Fix Summer Hair Texture Issues

The good news? A few tweaks to your routine can make a big difference.

At U&K Salon, we recommend:

• Hydrating shampoo and conditioner

  Go for sulfate-free formulas with added moisture.

• Weekly masks or treatments

  A once-a-week deep treatment helps restore softness and manageability.

• Skip the hot tools

  Air dry when you can—or at least use a heat protectant.

• Protective styles

  Braids, buns, and ponytails help keep your hair in check and reduce sun exposure.

• Book a professional treatment

  Our Japanese Hita Treatment and deep-conditioning services restore shine and smoothness without heaviness.

💬 Q&A: Your Summer Hair Questions Answered

Q: Is it normal for my black hair to look brown in the sun?

A: Yes! Sunlight breaks down melanin, and even dark hair will start to show reddish or golden tones under UV exposure.

Q: Can I reverse the lightening?

A: You can’t bring back lost pigment, but you can tone, gloss, or color over it to restore depth. We offer gentle options to refresh your look.

Q: What products should I use to fight frizz?

A: Look for:

• Leave-in conditioners

• Serums with UV protection

• Lightweight, sulfate-free shampoos

Q: Is summer damage worse for certain hair types?

A: Thicker or straighter hair types—like many of our clients’—may experience faster texture changes when the cuticle is exposed. That’s why we focus on Japanese hair care techniques designed to restore and protect your hair from the inside out.
