Kristin Ess Biotin Deep Conditioner 10 oz — Strengthen & Repair, Sulfate-Free Color Safe

Kristin Ess Biotin Deep Conditioner is a fortifying, biotin-enriched treatment that strengthens strands, reduces breakage, and deeply moisturizes dry or damaged hair.

This rich 10 oz deep conditioner blends biotin with amino acids to reinforce hair structure, smooth the cuticle, and improve manageability without sulfates or harsh ingredients. Designed for color-treated and chemically processed hair, the formula adds moisture and resilience while remaining vegan and suitable for multiple hair textures. Use it as a weekly intensive treatment or regular conditioner to help hair look fuller, shinier, and less prone to split ends.

How does this conditioner help fragile or thinning hair?

The biotin and amino acid combination supports keratin-building processes and helps reinforce weak points along each strand. By adding targeted nourishment and improving elasticity, it reduces the likelihood of breakage from brushing or styling. The effect is hair that appears thicker and shows fewer break points over time when used consistently.

• Biotin to support hair strength and visible fullness
• Amino acids that reinforce and repair strand structure
• Deep moisture to reduce brittleness and split ends

Will it work on color-treated or heat‑damaged hair?

Yes — the sulfate-free, color-safe formula is gentle on dyed and highlighted hair while delivering reparative moisture. It helps smooth the cuticle, which can restore shine and reduce the dull, rough texture that often follows color and heat processes. Regular use helps maintain vibrancy and improves the overall appearance of processed hair.

• Sulfate-free to protect color longevity and prevent fading
• Hydrating ingredients to replenish moisture lost during processing
• Cuticle-smoothing action for added shine and softness

How should I use it for best results?

Apply after shampooing to clean, towel-dried hair, working the conditioner from mid-lengths to ends and leaving it on for several minutes to allow penetration. For an intensive repair treatment, use a generous amount and let it sit 5–10 minutes under a warm towel or shower cap before rinsing. Rinse thoroughly and style as usual; reduce frequency if hair feels weighed down.

• Use weekly as a deep treatment or 2–3 times weekly as a regular conditioner
• Leave on 3–10 minutes depending on damage level and hair porosity
• Pair with a gentle, sulfate-free shampoo for optimal color care

What hair types benefit most from this deep conditioner?

The lightweight but nourishing formula suits a broad range of textures — from fine and straight to curly and coily — especially when hair is dry, brittle, or chemically treated. It restores softness and manageability without heavy residue when used in recommended amounts. People seeking to reduce breakage and improve visible thickness will notice the most benefit.

• Fine to thick hair needing strengthening and humidity resistance
• Wavy, curly, or over-processed hair requiring extra moisture
• Anyone wanting a vegan, color-safe strengthening treatment

Who is this for: Kristin Ess Biotin Deep Conditioner is made for people who want to strengthen and restore dry, damaged, or thinning hair while protecting color. It fits those who prefer vegan, sulfate-free products and need a versatile conditioner that can act as both a weekly intensive mask and a regular strengthening conditioner for everyday styling routines.
