Biolage Hydra Source Leave-In Cream for Dry & Color-Treated Hair, 6.8 fl oz — Moisturizing & Anti-Frizz

Biolage Hydra Source Leave-In Cream is a lightweight, leave-on treatment that instantly replenishes moisture, helps seal split ends and smooths dry hair with micro-filtered aloe vera and fermented hyaluronic acid.

Designed for thirsty, dry or color-treated hair, this daily leave-in cream delivers targeted hydration without weighing strands down. The formula pairs micro-dosed aloe vera with a fermented form of hyaluronic acid that penetrates fiber surfaces to condition, polish cuticles and reduce frizz. Packaged in a mostly paper tube to lower plastic use, the cream is vegan, free from parabens, mineral oil and artificial colorants, and Leaping Bunny certified.

How quickly will I notice softer, less frizzy hair?

Most users report hair feeling noticeably softer after the first application because the concentrated moisturizers smooth the cuticle and add slip for easier detangling. Over repeated use, hair looks shinier and frizz is visibly reduced as the leave-in maintains surface hydration.

• Instant slip for easier combing and reduced breakage
• Visible smoothing effect after a single use
• Improved shine with continued application

Will it weigh down fine or thin hair?

The micro-dosed formula is engineered to hydrate without heaviness by delivering small amounts of concentrated humectants. Apply a small quantity, focusing on mid-lengths and ends; fine hair benefits from the conditioning action without a greasy finish when used sparingly.

• Small amount avoids buildup on roots
• Works best when applied to damp hair and combed through
• Reapply lightly to dry ends for spot control

How does the product help with split ends and breakage?

The leave-in seals cuticle edges and temporarily smooths split tips to reduce visible fraying and mechanical damage during styling. By restoring surface hydration, the formula lowers friction between strands, which helps prevent future breakage from brushing and heat styling.

• Seals and smooths split ends for a tidier look
• Reduces friction to limit breakage during styling
• Supports healthier-looking growth by minimizing strand damage

Is it safe for colored or chemically treated hair?

Yes—this leave-in is suitable for color-treated and chemically processed hair, offering gentle hydration without harsh additives like parabens or mineral oil. Its lightweight, vegan formula helps preserve color vibrancy while restoring moisture balance.

• Formulated without parabens, mineral oil, or colorants
• Vegan and cruelty-free (Leaping Bunny approved)
• Helps maintain color shine with regular use

Who is this for: Biolage Hydra Source Leave-In Cream is ideal for people with dry, frizz-prone, or damaged hair who want a fast-acting, low-residue hydrator. It works well for those who heat style or color their hair and need a daily product to soften ends, smooth cuticles and reduce breakage without heavy buildup. If you prefer eco-minded packaging and a gentle, vegan formula, this leave-in cream fits into a routine for improved manageability and shine.

How to use: After shampooing and conditioning with Hydra Source products, towel-dry hair. Work a small amount through damp lengths and ends, comb through, and style as desired. For extra control, reapply a small amount to dry ends.
