Think it's just your skin that needs hydration? Think again! Water makes up 25% of our hair, but styling, heat and sun can dehydrate it, resulting in lifeless, lacklustre locks. But with our Advance Techniques Hydra Boost Leave-In Treatment, you can treat your parched scalp and weak strands to 8x the hydration.*

Product specification:

• Hydrating leave-in treatment for hair and scalp.
• Formulated with hyaluronic and amino acid complex.
• Part of the Advance Techniques Hydra Boost collection.
• Size: 50ml.

How to Use:

Apply to damp scalp post-wash, or to dry scalp overnight and rinse in the morning. For optimal results, apply your treatment to your scalp with our Advance Techniques Scalp Massager.

*When you use the shampoo, conditioner and leave-in treatment together.
