Surprising as it may sound, your hair can lose as much as 30% of moisture during the summer.
Sound familiar? You spend the summer soaking in the sun, going into pools, and enjoying the breezy beaches, only to find your hair feeling straw-like and brittle by mid-July.
If you’ve been conditioning it, blaming the heat alone, then it’s time for a wake up call. In this guide, you will discover the more nuanced reasons heat isn’t the only reason your hair feels drier in the summer.
This article is for you if:
- You struggle with managing frizz, dry hair, or split ends.
- You often color or bleach your hair, swim, or use heated styling appliances.
- You want actionable insights from reputable professionals in hair care.
Let us break the facts down for you.
Why Your Hair Feels Dry in Summer
Not Just The Heat: What Really Happens
It is one part of the equation. In reality, several factors combine to dehydrate your hair:
- UV radiation affects the outer covering of the hair (cuticle) and causes damage which leads to dullness and increased porosity.
- Dry air is a moisture thief. This is much worse in desert or hot inland areas.
- Wind exposure causes friction and weakens the strands.
- Chlorine and salt water strip natural oils and roughens the hair shaft.
When you combine this with increased sun exposure, sweat, and frequent washing, it creates a perfect storm for dehydration.
What Most People Get Wrong About Summer Hair Damage
One thing most people do is start washing more often simply because the hair “feels dirty” during the hot weather. This is a common misconception and the truth is overwashing is one of the biggest causes of dry, frizzy hair.
Here’s what’s behind the claim:
- Shampoos not only cleanse but also strips the hair of natural oils.
- Daily washing, especially with harsh products, can disrupt your scalp’s oil equilibrium.
- In the absence of an oil protecting barrier, hair is more susceptible to faster moisture loss.
Blaming the sun for damage and neglecting the roots where damage truly starts, in your shower!
3 For You To Consider The Most Surprising Ones That Make Your Hair Drier In The Summer
You may inadvertently be damaging your hair health. These summer beauty blunders are the most common:
- Washing the hair too many times: Excess shampooing promotes oil and moisture depletion, especially when done daily.
- Did not cover hair with sunscreen: Like skin, hair also requires protection from the sun.
- Hot styling after being out in the sun: Hot styling dry hair will lead to breakage.
This is important to note because your hair’s moisture barrier is likely already diminished during summer.
Therefore, gentle care will be most suitable.
How We Retain Moisture in Hair
Hair Porosity Types Walk Through
| Hair Attribute | Description | Risks During Warm Weather | Recommended Hair Care |
|---|---|---|---|
| Low | Cuticle bound tightly. Thus, water is repelled | High chance of product residue | Lightweight hydrators |
| Medium | Balance in moisture both absorbed and lost | Dryness, to an extent | Regular deep treatment |
| High | Cuticle open, absorbs quickly | Loss of moisture (as it’s absorbed) | Use sealants like protein treatments |
How Issues Created In July Are Exaggerated With Heat Components
- High porosity hair loses internal moisture rapidly when exposed to heat.
- Low porosity hair on the other end may end up trapping sweat along with products leading to a lackluster look.
Try the “float test.” Simply drop a clean strand of hair over a glass full of water and check if it sinks quickly. Sinking suggests high porosity.
