Key Takeaways

  • Understanding the difference between fine hair and thinning hair is the first step to finding the right hair routine.
  • Densifying products work by strengthening and plumping existing strands for immediate fullness and reduced breakage.
  • A targeted regimen using the Densifique Shampoo, Conditioner, and Mousse provides both instant volume and long-term thickness.

Understanding your hair type is the secret to unlocking visibly fuller hair. By the end of this guide, you will understand the science behind thinning hair and know exactly how to build a routine that supports thicker hair.


Do I have Fine Hair or Thinning Hair?

While these terms are often used interchangeably, they actually refer to two different hair characteristics. Understanding which one you have—or if you have both—will help you choose the most effective care routine.

Fine hair refers to the actual diameter of each individual hair strand. If your individual strands are smaller in circumference than average, your hair is considered fine. This hair type is largely determined by genetics. Because the strands are delicate, they can easily become weighed down by heavy products, making volume difficult to maintain.

Thinning hair, on the other hand, refers to the overall density of the hair on your scalp. This means there are fewer hair follicles actively producing hair, or the hair is falling out at a faster rate than it is growing in. Thinning can be caused by a variety of factors, including stress, hormonal changes, aging, or environmental stressors.


How to Build a Densifying Hair Care Routine for Thinning Hair

When addressing thinness, the goal is twofold: you want to create immediate fuller looking hair while also supporting the long-term health and density of the hair fiber. Infused with hyaluronic acid, gluco peptide, and ceramides, the Kérastase Densifique collection is formulated to strengthen thinning hair and improve density.

Step 1: Cleanse and Strengthen

A great volumizing routine always begins in the shower. When hair is fine or thinning, excess oil, product buildup, and environmental impurities can easily weigh it down. Starting with a clarifying yet gentle cleanse is essential for creating a weightless foundation.

The Densifique Shampoo is designed to gently cleanse the scalp while adding body and tone to the hair fiber and strengthening the hair to prevent future breakage.

Step 2: Condition and Plump

Many people with fine hair tend to skip conditioner, fearing it will leave their hair flat and greasy. However, delicate strands still require hydration and protection to prevent breakage. The key is choosing a formula that plumps the hair rather than coating it in heavy silicones.

Applying the Densifique Conditioner from the mid-lengths to the ends provides the perfect balance of moisture and texture. This lightweight formula enhances the hair's natural resilience, making it more resistant to breakage while visibly increasing the fullness of each strand.

Step 3: Style for Lasting Volume

The final step in your routine is where you lock in that coveted lift. Styling products for fine hair need to provide structure and hold without creating a stiff or crunchy texture.

Incorporating the Densifique Mousse into your damp hair before blow-drying is an excellent way to build weightless volume. This densifying mousse expands the hair fiber from the inside out, providing a noticeable boost in body and bounce. Focus the application at the roots for maximum lift, and comb the remaining product through to the ends for overall thickness.
