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

This shampoo combines quinine extract and a B-vitamin complex to fortify hair fibers while respecting the scalp. Designed for people experiencing hereditary or reactional hair thinning—such as shedding from stress, postpartum change, diet, or fatigue—the biodegradable formula removes buildup without silicones or SLS, helping hair feel fuller and less prone to breakage.

How does this shampoo help hair that feels thin?

The formula works on the hair fiber and scalp environment: quinine tones and strengthens keratin while B vitamins support the active effect of the plant extract. It cleanses gently so hair is less weighed down, making strands appear thicker and more resilient to daily breakage.

• Quinine extract to tone and reinforce hair structure.
• B-vitamin complex (B5, B6, B8) to boost quinine’s efficacy.
• Sulfate- and silicone-free base for lightweight cleansing.
• Biodegradable and vegan formulation for eco-conscious use.

When should I expect to see results and how should I use it?

Individual responses vary, but regular use as part of a thinning-hair routine supports visible strength and reduced breakage over time. Apply to wet hair, massage into the scalp to cleanse, then rinse; follow with a complementary conditioner or targeted strengthening products for best outcomes.

• Use 2–3 times weekly or as part of your regular wash schedule.
• Pair with Klorane Conditioner with Quinine and B Vitamins for added care.
• For intensified care, combine with Klorane Keratin Strength Fortifying Spray or supplements.
• Massage scalp to stimulate microcirculation during application.

Is this safe for sensitive scalps and everyday routines?

The shampoo is formulated without harsh sulfates and silicones, reducing irritation risk while remaining effective at removing oil and impurities. Its plant-based, dermatologist-tested approach aims to be well tolerated by most users, but patch testing is recommended for very sensitive skin.

• SLS-free and silicone-free to minimize stripping and buildup.
• Dermatologist-tested to support scalp compatibility.
• Vegan and biodegradable for gentler environmental impact.
• Suitable for both men and women experiencing hereditary or reactional thinning.

What ingredients should I look for and what should I avoid?

This shampoo highlights quinine and a B-vitamin blend as active botanical allies and intentionally omits common irritants like sodium lauryl sulfate and silicones. If you follow other treatments, check ingredient lists to prevent overlapping aggressive actives and consult a professional for medical hair-loss therapies.

• Key actives: quinine extract, vitamin B5 (panthenol), B6, and B8 (biotin).
• Free of SLS, silicones, and animal-derived ingredients.
• Biodegradable surfactants to reduce environmental impact.
• Compatible with Klorane topical and supplemental hair-strength routines.

Who this is for: Klorane Strengthening Shampoo with Quinine is suited to adults—men and women—who want a plant-based, dermatologist-tested shampoo that gently cleanses while supporting thicker-feeling hair. It’s an option for those experiencing gradual hereditary thinning or temporary, reactional hair loss from life events like stress or postpartum change, and for anyone seeking sulfate-free, eco-aware hair care to integrate with targeted conditioners or treatments.
