LA BIOSTHETIQUE Hydrating Drops RT 30ml

A 30ml moisture concentrate from the Structure Repair range. This is the bottle for hair that has gone dry and inelastic from colour, heat styling or weather, where a conditioner on its own is no longer shifting it. It is used in drops, either on its own or stirred into another product.

The actives

• Long-chain hyaluronic acid — film-forming; hydrates and smooths the cuticle on the outside of the hair.
• Low-molecular hyaluronic acid — penetrates the hair and binds moisture inside it.
• Red sea grass — supplies further moisture and is where much of the shine comes from.

How to use it

• As a leave-in — apply the drops to towel-dried hair and do not rinse out.
• As a care booster — add to your hair mask or conditioner at a ratio of three parts drops to ten parts product, mix well, then rinse out after the usual processing time.

Worth knowing

The 3:10 ratio is built around the Structure Repair Nourishing Mask and Nourishing Conditioner, so those are the natural partners. A 30ml bottle looks small, but at a few drops a use it lasts.
