Sun, pool water, and humidity are the three biggest threats to hair health during summer. Each one causes a different type of damage. Most guests don’t realize it until they’re already dealing with dryness, breakage, faded color, or texture that simply won’t cooperate.
This guide covers what summer does to your hair, how to recognize the signs, and exactly what to do to protect it so it stays healthy, shiny, and manageable all season long.

What the Sun Does to Your Hair
UV rays affect hair the same way they affect skin, they break down structure, fade color, and strip moisture over time.
The outer layer of the hair shaft (the cuticle) acts as a protective barrier. With repeated UV exposure, that barrier weakens. The result:
- dryness and brittleness
- frizz and puffiness
- color that looks dull, faded, or uneven
- split ends appearing sooner than expected
- blonde or highlighted hair shifting brassy or orange
Natural hair isn’t immune. Even guests who haven’t colored their hair notice increased dryness and texture changes after a summer of sun exposure.
The most effective protection is a UV-shielding leave-in or finishing spray applied before outdoor activity. Your stylist can recommend the right option for your texture and finish.
What Chlorine Does to Your Hair
Pool water is one of the most damaging things hair encounters during summer, and most guests underestimate it.
Chlorine is designed to disinfect water by breaking down organic compounds, including the proteins and oils that keep hair healthy. After repeated pool exposure, hair often becomes:
- rough, porous, and prone to tangling
- dull and lifeless
- more fragile and prone to breakage
- brassy, orange-shifted, or greenish if color-treated
The simplest habit that makes a real difference: wet your hair thoroughly with fresh water before entering the pool. Hair that’s already saturated absorbs significantly less chlorine. Rinse again immediately after leaving the pool.
L’Oréal Professionnel Metal Detox is a favorite for guests who swim regularly. It neutralizes the metal particles that accumulate in hair from pool and hard water, preventing the dullness and structural weakening that builds up over a swim season.
What Humidity Does to Your Hair
Humidity causes the hair shaft to swell as it absorbs moisture from the air. This disrupts the cuticle and leads to frizz, puffiness, and styles that fall faster than expected.
Guests with fine hair, naturally wavy or curly hair, or chemically treated hair tend to notice this most, but humidity affects nearly every hair type during summer months.
- Blowouts may not last as long as they did in cooler months
- Smooth styles become puffy throughout the day
- Hair that feels manageable in winter suddenly seems unpredictable
A professional smoothing treatment such as a Brazilian Blowout reduces frizz and helps hair behave more predictably for up to three months. Anti-humidity finishing sprays help set a style day-to-day. And the right shampoo and conditioner make a noticeable difference in how the hair responds to humid air over time.
If you’ve been struggling with frizz all season, ask your stylist whether a smoothing treatment would be a good fit for your hair type.

Signs Your Hair Is Struggling with Summer Stress
A few things to watch for as the season progresses:
- Hair feels rougher or more coarse than it did in spring
- Color looks dull, faded, or shifted from its original tone
- Split ends are appearing faster than usual
- Hair tangles more easily, especially after washing
- Blowouts and styles aren’t lasting as long
- Hair feels dry even right after conditioning
If you’re noticing more than one of these signs, your hair is likely dealing with cumulative summer stress. A professional treatment, combined with the right home care, can restore moisture, rebuild strength, and protect the hair for the rest of the season.
How to Build a Summer Hair Care Routine
Use a sulfate-free, color-safe shampoo and conditioner
Sulfate-heavy shampoos strip moisture and color with every wash. Switching to a gentler formula is one of the highest-impact changes you can make. Oribe Gold Lust shampoo and conditioner is one of our most recommended home care systems, it restores moisture, supports strength, and maintains a polished finish without weighing hair down.
Apply UV protection before going outside
Just as SPF is non-negotiable for skin, UV protection should be part of your hair routine during summer. A leave-in or finishing spray with UV filters helps shield the hair from prolonged sun exposure. Ask your stylist what they recommend for your texture.
Deep condition once a week
A weekly mask replenishes the moisture that sun, heat, and pool exposure pull out over time. The right formula depends on your hair type, your stylist can recommend what will work best for you specifically.
Rinse pool or salt water immediately
Don’t let chlorinated or salt water sit in your hair longer than necessary. Rinse as soon as possible after leaving the water, then cleanse and condition. Keeping a small bottle of leave-in conditioner in your beach or pool bag helps protect hair before you get back to the shower.
Use heat tools wisely
Summer heat is already taxing on hair. When possible, let hair air dry or use a diffuser on a low heat setting. Always apply a heat protectant before using any hot tools. This is especially important when hair is already more dry from seasonal stress.
When to Book a Professional Treatment
At-home care goes a long way, but some summer damage requires professional attention.
If your hair feels rougher or more porous than it did in spring, if color is fading faster than expected, or if breakage is increasing… a professional treatment can reset the hair’s health and protect it going forward. Services to discuss with your stylist:
- Bond repair treatment: rebuilds the internal structure of hair damaged by bleach, heat, or chemical processing
- Hydrating in-salon mask: deep moisture restoration in a single appointment
- Gloss or toner service: refreshes color, adds high shine, and smooths the cuticle
- Brazilian Blowout: smooths and seals the cuticle for up to three months of reduced frizz
Your stylist can assess the current condition of your hair and recommend what makes the most sense for the rest of your summer.
