Extremely dry hair: tips and treatments for intensive care

Extremely dry hair feels different from ordinarily dry hair. It breaks easily, has no elasticity, feels rough even after washing, and does not respond to regular moisturizing products. This is a sign that the hair cuticle is severely damaged and that your hair needs both moisture and protein to recover.

Here, we explain what causes extremely dry hair, how to treat it, and which products work best.

What causes extremely dry hair?

Extremely dry hair occurs when the hair cuticle is damaged to the point that it can neither absorb nor retain moisture effectively. The most common causes are:

  • Bleaching and coloring: Chemical processes that open the cuticle significantly and break down the hair's internal protein structure.
  • Repeated heat styling: Daily use of straighteners and curling irons without heat protection evaporates moisture and permanently damages the cuticle.
  • Using the wrong products over a long period: Shampoos with SLS/SLES strip the hair of its natural oils wash after wash.
  • Environmental stressors: Sun, salt water and chlorinated water, dry indoor air, and cold break down the cuticle's lipid layer.

Moisture and protein: both are essential

Extremely dry hair often lacks both moisture and protein. Moisture gives it elasticity and softness, while protein provides strength and structure. If you add moisture without protein, your hair will feel soft but still break easily. If you add protein without moisture, your hair will feel stiff and brittle. Learn more about finding the right balance in our guide to protein and moisture balance in your hair.

Intensive treatment for extremely dry hair

When your hair is extremely dry, a regular hair mask isn't enough. You need intensive care with a high concentration of moisturizing and repairing ingredients. FOAM's Deep Moisture Treat Duo is formulated specifically for dry and damaged hair, providing deep hydration combined with nourishing oils.

For even better results, apply a hair mask overnight. The extended exposure time gives the ingredients time to penetrate deep into the hair shaft.

Switch shampoos right away

The first and most important step is to switch to a sulfate-free shampoo. FOAM's Forest Treat is formulated for dry and damaged hair with Glycerin, Vitis Vinifera Seed Oil, and Vaccinium Myrtillus Seed Oil to provide moisture and nourishment without weighing your hair down. Learn more in our guide to shampoo for dry hair.

Vanliga frågor

Is there an adjustment period when switching to solid shampoo? +
If you’ve previously used conventional shampoo with silicones, your hair may need 1–2 weeks to adjust. During this time, silicone residue is cleared away and the scalp’s natural oil production becomes balanced, resulting in healthier, more natural-looking hair.
How long does a shampoo bar last? +
A shampoo bar from FOAM lasts a long time and often lasts as long as at least 2 regular-sized bottles of shampoo.
Store the shampoo bar somewhere dry between uses to make it last longer.
How do you store a shampoo bar in the shower? +
To make the bar last as long as possible, the most important thing is to let it dry thoroughly between washes. Store it on a well-ventilated soap dish with drainage, or hang it in a shampoo pouch in the shower so the water can drain away.
