Summer puts your hair and beard to the test.
Between the sun, heat, perspiration, salt and chlorine, the hair fibre can quickly lose its comfort and balance. The result: drier hair, a coarser beard, and a feeling of discomfort on the scalp or skin.
To understand why, we first need to understand how hair and beard hair are structured.

Understanding the Structure of Hair and Beard Hair
Both scalp hair and beard hair are primarily made up of keratin, a naturally resilient protein that provides structure and flexibility.
Each strand has an outer layer called the cuticle.
Its role is essential: it protects the core of the hair from external aggressors and helps retain its natural moisture.
When this protective barrier is weakened, the hair becomes drier, more brittle and loses its flexibility.
Beard hair has an additional characteristic: it is often thicker and more porous than scalp hair. It therefore has a harder time retaining moisture and can become coarse more quickly when exposed to heat.
The Effects of Heat and Sun Exposure
Prolonged exposure to the sun directly affects the hair fibre.
UV rays damage the cuticle and gradually weaken the keratin.
The hair then loses elasticity and becomes drier. Longer hair may appear dull, become harder to style or break more easily.
Heat also increases the evaporation of natural moisture.
The scalp can become more sensitive, while the beard may cause discomfort or a feeling of tightness on the skin underneath.
Sea salt and chlorine can further amplify these effects by drying out the hair fibre even more.
The result:
less flexibility,
more dryness,
and an overall feeling of tired, weakened hair and beard hair.
The Right Habits to Protect Your Hair and Beard
During periods of high heat, the goal isn’t to overload the hair with products, but to preserve its natural balance and moisture levels.
A few simple habits can help limit the effects of summer exposure:
- Rinse your hair and beard after exposure to salt water or chlorine to remove drying residues.
- Use gentle, nourishing shampoos that cleanse without further weakening the hair fibre.
- Occasionally incorporate restorative masks to help the hair regain softness and comfort after prolonged sun exposure.
- Choose lightweight, nourishing oils for your beard and longer hair, such as avocado oil, known for its softening and protective properties.
- Opt for products enriched with natural ingredients such as mango butter, valued for its nourishing qualities and ability to help maintain hair softness.
- Keep the scalp and the skin beneath the beard properly moisturised.
- Avoid excessive use of heated styling tools when your hair is already exposed to high outdoor temperatures.
Consistency is key: a few appropriate, regular steps will often provide greater benefits than an overly aggressive or overloaded routine.
