Anyone with fine, thin or limp hair that tangles easily and loses its shape during styling. It suits straight and wavy fine hair best, where heavier creams would flatten the root.

It is a consumer-friendly salon brand product: no mixing or professional technique needed, just a leave-in applied after washing.

Fine hair usually has two problems at once: it tangles and snaps easily, yet most conditioning products leave it limp. AddPower Strengthening Fluid tackles both with a protein-based leave-in that is light enough to skip rinsing. The rice protein coats and fortifies the hair fibre so each strand feels thicker and holds up better under the brush and dryer, while the fluid base detangles and adds just enough moisture.

Because it is the Start step of KMS's AddPower system, it is designed to sit under the AddPower Thickening Spray or any other volumizing styler without competing with it.

• Shampoo and condition as usual, then towel-dry hair.
• Work a small amount of the fluid through the damp hair.
• Leave in. Do not rinse.
• Style as desired, or let hair air-dry.

Pros:

• Light texture that doesn't flatten fine hair
• Detangles wet hair, which cuts down on breakage when combing
• Rice protein gives fine strands a firmer, thicker feel
• Doubles as a leave-in conditioner or air-dry lotion, so it can replace a separate product

Cons:

• Too light to soften very thick, coarse or very dry hair
• Contains fragrance and limonene, which may not suit sensitive scalps
• No hold of its own: you'll still want a styler if you need volume that lasts
