Key takeaways
- Volume starts at the roots: that's where you need to act.
- An oily scalp and overly rich care products are the main causes of flat hair.
- Drying your hair upside down and a lightweight volumising product lift the roots.
- Apply care products to the lengths, never to the roots.
- A dedicated volume routine maintains the effect over time.
Why is my hair flat?
- Fine hair, which does not hold volume well.
- An oily scalp: sebum weighs hair down and makes it lie flat.
- Overly rich care products or products applied to the roots.
- Drying that has not lifted the roots.
- Humidity, which causes your style to fall flat.
Steps that add volume
- Dry your hair upside down, using your fingers at the roots.
- Apply a lightweight volumising mousse or spray to the roots of damp hair.
- Use a round brush to lift the roots when blow-drying.
- A volumising powder at the roots revives volume during the day.
- Avoid touching your hair too much, as this makes it lie flat.
Which care products should you choose (and avoid)?
Choose lightweight care products that do not weigh hair down, applying them only to the lengths. Avoid very rich masks, excessive oils and heavy silicones. A balancing shampoo is useful if your scalp becomes oily quickly.
