Biolage points this mousse at fine hair that falls flat and needs body and height, while noting it suits all hair textures and colour-treated hair. It is for people who want visible volume and a style that keeps its shape, but who still want hair to feel soft and move naturally.

It is a salon-brand product that is simple to use at home as part of a normal wash, condition and blow-dry routine. Anyone looking for strong, sculpting hold for updos or defined curls will likely want a firmer styler alongside it.

Fine hair tends to lose volume quickly, and many mousses make up for it by leaving hair stiff. Bodifying Mousse is built to plump hair for body and height and help a blow-dry keep its shape while the hair stays soft to the touch, so the result reads as natural volume rather than product. It is the updated version of Biolage's previous styling mousse, now in a more sustainable can, and it slots into any Biolage cleanse-and-condition routine as the styling step.

Biolage's directions:

• Shake the can well.
• Turn the can upside down and release the mousse into your hand.
• Rub your hands together to spread the product evenly.
• Apply to clean, damp hair and style as desired.

What to expect from it:

• Pro: adds lift and body at the roots of fine or flat hair without leaving it stiff or crunchy.
• Pro: whipped foam is easy to spread evenly through damp hair before blow-drying.
• Pro: suitable for colour-treated hair.
• Con: it is a light, flexible hold, not a strong-hold mousse, so heavy or very long hair and humid days may need an extra styler or hairspray.
• Con: it is an extremely flammable aerosol, so keep it away from heat and flames and don't pack it in carry-on luggage.
• Con: contains fragrance and several listed fragrance allergens (such as limonene, linalool and coumarin).
