Klorane Strengthening Shampoo with Quinine, 13.5 fl oz — Sulfate-Free for Thinning Hair

Klorane Strengthening Shampoo with Quinine is a sulfate-free, plant-based shampoo formulated to cleanse gently while supporting visibly stronger, thicker-feeling hair for men and women experiencing thinning.

This dermatologist-tested shampoo combines quinine extract with a B-vitamin complex and edelweiss to help reduce breakage and support hair that looks and feels fuller. The biodegradable, vegan formula is free from SLS and silicones and was created for people facing hereditary or reactional hair thinning caused by genetics, stress, diet changes, fatigue, or postpartum shedding. Use it as a daily cleanser or as part of a targeted routine alongside Klorane conditioners and supplements designed to strengthen and fortify hair structure.

How does this shampoo help hair that is thinning?

The formula aims to reinforce hair fibers and decrease fragility so strands appear thicker and handle daily styling better. Quinine extract works with B vitamins to tone and strengthen the hair fiber, while a gentle cleansing base removes dirt without stripping natural oils.

• Quinine extract to strengthen and tone hair fibers.
• B-complex (B5, B6, B8) to improve quinine activity and hair resilience.
• Gentle surfactants that clean without harsh stripping.
• Biodegradable, silicone- and SLS-free formulation for gentler care.

When should I use Klorane Quinine Shampoo and how often?

This shampoo is suitable for regular use and can be incorporated into a daily or alternate-day routine depending on scalp needs and styling habits. For best results, massage into wet hair, leave for a minute to allow active ingredients to act, then rinse; follow with the matching Klorane conditioner or targeted treatments if desired.

• Use daily or every other wash based on scalp sensitivity.
• Massage into scalp and hair, leave briefly, then rinse thoroughly.
• Pair with Klorane Quinine conditioner and strengthening treatments.
• Combine with dietary or topical supports for comprehensive care.

Is this safe for color-treated or sensitive scalps?

The gentle, sulfate-free base and absence of silicones make the shampoo appropriate for many color-treated and sensitive scalps, though individual reactions vary. Because it avoids harsh sulfates and uses plant-derived actives, it minimizes the risk of additional drying or buildup that can affect treated hair.

• Sulfate-free cleansing reduces color fade risk compared with SLS shampoos.
• Silicone-free formula avoids residue that can weigh hair down.
• Plant-derived, biodegradable ingredients for milder scalp contact.
• Dermatologist-tested, but patch testing is recommended for known sensitivities.

Which products complement this shampoo in a strengthening routine?

To amplify strengthening and thickening effects, combine the shampoo with Klorane's conditioner with quinine and B vitamins, leave-in fortifying sprays, or oral supplements targeting hair and nails. Layering topical and nutritional supports helps address both hair fiber resilience and overall hair health from multiple angles.

• Klorane Conditioner with Quinine & B Vitamins for added detangling and strength.
• Klorane Keratin Strength Fortifying Spray for styling protection and fortification.
• Klorane Keratin Caps supplement to support hair and nail nutrition.
• Use as part of a balanced hair-care routine with gentle styling practices.

Who is this for: Klorane Strengthening Shampoo with Quinine is intended for adults—men and women—seeking a plant-based, dermatologist-tested shampoo to help reduce hair breakage and support thicker-feeling hair. It suits those experiencing hereditary or temporary (reactional) thinning due to stress, lifestyle changes, or postpartum shedding, and for anyone who prefers a biodegradable, SLS- and silicone-free cleansing option as part of a targeted strengthening regimen.
