Biolage Hydra Source Serum 90ML

Biolage Hydra Source Serum 90ml is a lightweight, water-based scalp and hair serum designed to bring lasting hydration to dry, thirsty hair. Infused with aloe vera and fermented hyaluronic acid, the formula helps to nourish the scalp while delivering moisture along the lengths, leaving hair feeling soft, supple and comfortably hydrated. The texture feels fresh and clean to the touch, making it a reassuring choice for those who prefer weightless care that doesn’t leave residue. Suitable for all hair types, including colour-treated hair and sensitive scalps, it fits easily into an existing haircare routine as a targeted hydration step.

Use this product after cleansing, on towel-dried hair, by parting the hair to expose the scalp and applying small drops directly where needed. Gently massage into the scalp, then smooth through the mid-lengths and ends before styling as usual. The serum may help hair look healthier and more conditioned over time, supporting a smoother, more manageable finish while giving the scalp a comfortable, moisturised feel.

How to Use:
Apply to clean, freshly washed hair. Towel-dry, then separate the hair into sections to expose the scalp. Apply one drop of the serum every inch or so along the scalp. Gently massage the product into the scalp, then smooth any excess through the lengths of the hair. Do not rinse and style as usual. The serum can also be applied to a clean, dry scalp and hair when needed.

Frequency:
Use as needed, following the product instructions or whenever the scalp and hair need additional hydration.

Application Technique:
Work on damp or dry hair, ensuring the scalp is clearly exposed before application. Use the fingertips to massage the serum into the scalp in small circular motions, then distribute through mid-lengths and ends for even hydration.

Best Practices:
Apply to clean hair for best results and allow the serum to absorb fully before using other styling products. Use a small amount to avoid overloading the hair and focus on areas that feel particularly dry.

Safety Tips:
Avoid contact with the eyes; if contact occurs, rinse immediately with water. Use externally only and discontinue use if irritation occurs. Keep out of reach of children and follow any additional guidance on the packaging.
