Kérastase Blond Absolu Hyaluronic Acid Hair Serum 50ml

A clear leave-in serum with 2% hyaluronic acid, the highest concentration Kérastase uses in any hair product. It hydrates lightened hair and nourishes the scalp at the same time, which makes it especially useful in the weeks after a blonding service.

Who it's for

• Bleached or lightened hair that feels dry, rough or fragile
• Blondes with a scalp that feels tight or dry after colour
• Other hair types wanting hydration, as it contains no purple or brightening pigment

Key benefits

• Hydrates hair and scalp instantly
• Helps repair damage from chemical services, heat and brushing
• Supports the scalp's moisture barrier
• Leaves hair softer, stronger and shinier

Key ingredients

• Hyaluronic acid (2%): draws in and holds moisture, fills weak spots in the fibre for a smoother cuticle and helps strengthen hair against future breakage

How to use

1. Shampoo and condition, then towel-dry.
2. Pump three to seven doses, depending on hair length.
3. Massage gently into the scalp, then work through mid-lengths and ends.
4. Do not rinse. Use two to three times a week.

Our stylists' tip

Apply it straight after your first wash post-lightening, when hair is at its most thirsty. For the scalp, part the hair in sections and press the serum along each part rather than rubbing it into the top layer only.
