Why does my hair fall flat so quickly?
Has your morning volume disappeared by midday? Several causes often combine: a scalp that becomes oily quickly, products that are too heavy, or styling that is not set.

Key takeaways
- Sebum is the number one cause: as it builds up, it weighs down the roots.
- Overly rich treatments or treatments applied to the roots weigh down the fibre.
- Styling that is not set falls flat with humidity and handling.
- Fine hair holds its shape less well and retains less volume.
- A balanced scalp helps volume last.
Why volume does not last
- An oily scalp that becomes oily again during the day.
- Heavy products (oils, silicones, rich treatments at the roots).
- Styling that is not set (no mousse, spray or suitable drying).
- Ambient humidity and touching your hair too much.
- Naturally fine hair.
How can you make volume last?
- Dry upside down and set the roots with a lightweight volumising product.
- Keep rich treatments for the lengths.
- Space out washes if your scalp tolerates it, using a balancing shampoo.
- Use dry shampoo at the roots during the day, sparingly.
- Avoid constantly handling your hair.
The role of the scalp
Un cuir chevelu qui produit beaucoup de sébum plaque rapidement les racines. Le rééquilibrer avec un shampooing adapté, sans le décaper, aide le volume à durer plus longtemps. Voir notre article sur le cuir chevelu gras.
