FUL Hyaluronic Acid Hair Serum 50ml

FUL Hyaluronic Acid Hair Serum (50ml) is a hydrating, lightweight, multi-use serum which promotes hydrated, smooth and frizz-free hair. The non-greasy formula helps the hair and scalp to retain moisture without weighing it down, and leaves the hair delightfully fragranced with a blend of rose, lychee, amber and cedarwood.

The formulation includes Hyaluronic Acid to lock in moisture on the scalp, Panthenol to condition the hair and seal in moisture on the hair and scalp, and Castor Oil to nourish and moisturise both hair and scalp. Betaine helps to reduce frizz whilst Glycerine leaves the hair soft. Free from mineral oil, sulphates and parabens. Cruelty-free & vegan-friendly.

Key Benefits:

• 5-in-1 serum for styling and treatment.
• Triple hydration complex adds moisture, smoothes hair and tames flyaways.
• Spot treatment for dry and flaky scalps.
• Lightweight non-greasy formula.
• On-the-go frizz control.

Directions of use:

• Dry Styling - apply a pea-sized amount of FUL Hyaluronic Acid Hair Serum and work through to your mid-lengths and ends to help hydrate and tame flyaways, then style as usual. Alternatively, use as a spot treatment for a dry scalp and to tame frizz and flyaways once your hair is styled.
• Wet Styling - after washing your hair as usual with your favourite FUL Shampoo and Conditioner, apply a pea-sized amount of FUL Hyaluronic Acid Hair Serum and work through the mid-lengths and ends. Style as usual for hydrated hair and minimised flyaways.
