This spray is aimed at anyone with fine, thin, or weak hair who wants more visible body without switching to a heavier mousse or gel. It works on damp hair before blow-drying, so it suits people who already blow-dry or heat-style regularly and want a thickening step that doubles as heat protection. KMS markets Add Power through professional salons, but the product itself requires no training or mixing — it's a straightforward spray-and-style step suitable for home use by any experience level, and the tagging shows it's positioned for both men and women.

Most thickening sprays only add texture; this one is built to do two jobs in the same step — reinforce fine strands with rice protein while shielding them from the heat tool you're about to reach for anyway. Because it's a spray rather than a cream or mousse, it distributes evenly through towel-dried hair without weighing roots down, which matters most for hair that's already limp.

• Shake the bottle before use
• Spray evenly through towel-dried hair, focusing on roots for lift and mid-lengths for body
• Blow-dry and style as usual, using a round brush at the roots for extra lift if desired
• Can be lightly reapplied on dry hair to refresh volume through the day

• Pro: adds body to fine hair without the tackiness or weight of a mousse
• Pro: doubles as a heat protectant up to 200°C, so no separate spray is needed before blow-drying
• Con: leads with alcohol denat., which can leave hair feeling dry with very frequent use, especially on already-dry ends
• Con: heat protection is rated to 200°C — tools run hotter than that should be dialed back or a higher-rated protectant used
