Fuller, denser hair in a couple of spritzes. Biolage Full Rescue Densifying Leave-In Spray 250ml is a lightweight leave-in spray made especially for fine, weak hair that needs a boost of thickness and body. It instantly thickens the look and feel of your strands while detangling and controlling frizz, all without any greasy heaviness, so you get fuller-looking hair that still moves beautifully.

The density comes from a micro-dosed concentrate of rosemary oil and niacinamide, the same fortifying duo at the heart of the Full Rescue range. As well as thickening and softening, it helps tame flyaways, makes styling easier and supports a healthy scalp, so your hair feels silky soft and looks noticeably fuller after just one use*. It's the easy everyday step that gives fine hair the helping hand it needs.

What it does for fine, weak hair

Fine or weak hair often falls flat and lacks the body and density that makes a style feel full. This leave-in spray tackles that by instantly thickening the feel of each strand and adding fullness from the moment you apply it, while the fortifying ingredients support stronger, healthier-feeling hair over time. The result is hair that looks denser and fuller, detangles more easily and feels silky soft, all without the weight that flattens fine hair.

How to use it

Spray evenly through clean, towel-dried hair, focusing on the roots and lengths for maximum body. Comb through to detangle and distribute, then style as usual, there's no need to rinse. For the best results, use it alongside the matching Full Rescue shampoo and conditioner to get the full silky-soft, densifying benefit*. You'll find the rest of the range in our professional shampoo collection.

Who it's for

This one's for anyone with fine, weak or flat hair that needs instant thickness, body and softness, plus easier detangling and frizz control. It's suitable for colour-treated hair, and like every Biolage formula it's vegan with no animal-derived ingredients and certified cruelty-free under the Leaping Bunny programme. We've spent years helping clients in Codsall get the most out of fine and delicate hair, and a densifying leave-in like this is one of the simplest ways to add fullness between salon visits.

Build your strengthening routine

For the best results, use this spray as the leave-in step within the full Full Rescue system, alongside the shampoo, conditioner and mask.
