If your hair looks flat, your roots are becoming visible, grey hair is appearing between salon visits, or thinning areas are making your hairstyle look less dense, the right styling product can make a noticeable difference to your overall appearance.
But not every hair-thickening product works in the same way.
A styling powder is designed primarily to add texture, volume and a matte finish.
A hair fiber product works by creating the appearance of greater hair density in areas where existing hair is thinning.
A root concealer cream can cover visible grey roots and certain scalp areas.
A root touch-up spray is designed for fast temporary color coverage.
A volumizing mousse is primarily intended to create lift and fullness throughout the hairstyle.

Frequently Asked Questions
What is the best hair thickening product?
The best product depends on what you mean by “thickening.” Hair fibers are designed to create the appearance of greater density, while volumizing products such as mousse and styling powder primarily increase volume and texture.
What is the best product for thinning hair?
For the cosmetic appearance of thinning hair, hair building fibers can be useful when there is enough existing hair for the fibers to attach to. A scalp concealer can also reduce the visibility of exposed scalp.
Do hair fibers actually grow hair?
No. Hair fibers are cosmetic products that can make existing hair appear denser. They should not be considered hair-growth treatments.
Can hair fibers cover bald spots?
They can help reduce the appearance of some sparse areas, particularly when there is surrounding or remaining hair for the fibers to attach to. Completely hairless areas are more difficult to conceal naturally.
Which is better, hair fibers or hair powder?
Hair fibers are primarily designed to create a denser appearance, while styling powder is mainly designed for texture, root lift and volume.
What is the best product for grey roots?
L’Oréal Paris Magic Retouch is specifically designed for temporary root touch-up. ADOMOUR is another option when you prefer a cream-based scalp/root concealer.
