Biolage Ultra Hydra Source Deep Treatment Mask 16.9 fl oz — Vegan, Intense Hydration for Very Dry Thick Hair

This deep treatment combines micro-dosed cold-pressed Cupuaçu butter with filtered salicylic acid in a vegan, paraben-free base to replenish moisture, detangle heavy textures, and leave hair feeling softer without weighing it down. Packaged in a generous 16.9 fl oz size, the mask is designed for weekly use as part of the Ultra Hydra Source system to revive and smooth strands between salon visits.

How does this mask restore moisture to very dry, thick hair?

The formula delivers concentrated emollients that soften coarse cuticles and help strands retain water. Cupuaçu butter acts as a rich lipid source to improve slip and suppleness, while the mask’s conditioning agents help smooth the outer layer of the hair shaft for a silkier finish.

• Micro-dosed cold-pressed Cupuaçu butter for deep emollience
• Weight-balanced conditioning to avoid heaviness on thick hair
• Designed to improve softness and tactile smoothness

Why is filtered salicylic acid included, and what does it do?

Filtered salicylic acid supports scalp clarity and gentle surface exfoliation, which can help remove buildup that prevents moisturizers from penetrating. In this mask it’s used at levels safe for regular weekly treatment to enhance product absorption and leave both scalp and strands feeling cleaner and more receptive to hydration.

• Helps clear residue for better moisture uptake
• Promotes a smoother cuticle for increased shine
• Formulated for scalp and strand compatibility in thick textures

How should I use this mask to get the best results?

For optimal benefits, apply to freshly washed, wet hair and distribute evenly from mid-length to ends; leave on for 3–5 minutes, then rinse thoroughly. Use once weekly as a deep treatment or more often if hair is extremely dry, pairing with Ultra Hydra Source Shampoo for a full regimen.

• Apply to wet hair after shampooing
• Leave in for 3–5 minutes, then rinse completely
• Use weekly or as needed for added hydration

Is this mask suitable for color-treated or curly hair?

Yes — the vegan formula is free of parabens, mineral oil, and artificial colorants, making it safe for color-treated hair and supportive of curl definition by improving manageability and reducing frizz. The nourishing profile is particularly helpful for thick, textured curls that need extra slip and control.

• Color-safe and formulated without parabens
• Improves detangling and curl separation
• Helps reduce frizz while boosting shine

Who is this for: This treatment mask is tailored for people with very dry, thick, coarse, or curly hair looking for a concentrated weekly boost of hydration and manageability. It's a good choice for those who want salon-grade conditioning at home, prefer vegan and paraben-free formulations, and need a product that works alongside color services without adding heaviness.
