Baxter of California Fortifying Conditioner (Size Options)

The shampoo does the strengthening work - the conditioner is what makes it stick. The Baxter of California Fortifying Conditioner is the second half of a clinically tested system designed for fine, thinning, or weak hair, and it's where the moisturizing, detangling, and elasticity improvements happen. The same active trio from the shampoo - pea sprout extract, basil root culture extract, and hydrolyzed rice protein - carries through into the conditioner, so every wash reinforces the same strengthening and thickening story from two angles. Behentrimonium chloride and cetearyl alcohol deliver the smooth, manageable detangle that conditioner is supposed to provide, while panthenol adds moisture and flexibility to the hair fibre so it bends rather than breaks under tension. The result is hair that feels noticeably softer and more manageable after rinsing, looks thicker and fuller over time, and smells clean with the same invigorating mint finish as the shampoo. Sulfate, paraben, and phthalate-free. Clinically tested to increase hair fibre thickness and elasticity when used consistently as a system with the Fortifying Shampoo. *Please note: Packaging / label may vary for the 473ml size. 

Who's It For

The essential partner to the Fortifying Shampoo - designed for the same audience but delivering a different and complementary set of benefits. Ideal for:

• Anyone already using the Fortifying Shampoo who wants the full clinically tested system benefit - the clinical results are based on shampoo and conditioner used together
• Guys with fine, thinning, or weak hair who need a conditioner that moisturises and detangles without weighing hair down
• Anyone whose hair tangles easily, breaks during combing, or lacks the elasticity and flexibility it used to have
• Those who want a daily conditioner that actively works on hair strength rather than just adding softness
• All hair types - but specifically formulated to address the needs of weak or thinning hair 

Key Benefits

• Clinically tested to increase hair fibre thickness when used as a system with the Fortifying Shampoo
• Clinically tested to improve hair elasticity - hair that bends and flexes under tension rather than breaking
• Pea sprout extract continues the volumizing and thickening action from the shampoo through the conditioning step
• Basil root culture extract reinforces the hair fibre and improves strand integrity from root to tip
• Hydrolyzed rice protein fills and strengthens the hair shaft, adding body and improving texture
• Behentrimonium chloride provides smooth, frizz-free detangling without stripping the natural moisture balance
• Panthenol (Pro-Vitamin B5) improves hair elasticity and flexibility - reducing the breakage that comes with combing or styling fine hair
• Glycerin draws moisture into the hair fibre and holds it there for lasting softness and hydration
• Invigorating mint fragrance with menthol - fresh, clean, and consistent with the Fortifying Shampoo
• Sulfate, paraben, and phthalate-free - safe for daily use on all hair types
• Clinically tested, dermatologist tested, and barber approved 

Key Ingredients

• Pea Sprout Extract (Pisum Sativum) - Carries the volumizing and thickening benefit from the shampoo through the conditioning step, reinforcing hair density and fibre thickness with every wash cycle.
• Basil Root Culture Extract (Ocimum Basilicum Hairy Root Culture Extract) - A biotechnology-derived active that strengthens the hair strand and improves fibre integrity - working in the conditioner to reinforce what the shampoo has already begun.
• Hydrolyzed Rice Protein - Penetrates the hair shaft to fill structural gaps, add body, and improve the overall resilience and texture of fine or weakened hair. A key reason this conditioner adds visible thickness rather than just softness.
• Behentrimonium Chloride - A conditioning agent derived from rapeseed oil that smooths the hair cuticle, detangles effortlessly, and reduces frizz without weighing fine hair down - the workhorse of a conditioner formula.
• Panthenol (Pro-Vitamin B5) - Binds moisture throughout the hair fibre and improves elasticity - meaning hair stretches and flexes under tension rather than snapping. Particularly valuable for fine or brittle hair that's prone to breakage during styling.
• Glycerin - A humectant that draws moisture from the environment into the hair and holds it there, contributing to the soft, hydrated feel after rinsing and helping maintain moisture balance between washes. 

How To Use

After shampooing with the Baxter of California Fortifying Shampoo, squeeze excess water from hair. Apply a generous amount of conditioner from mid-lengths to ends - focus away from the scalp to avoid weighing fine hair down at the roots. Work through with fingers or a wide-tooth comb to ensure even distribution. Leave on for 1 to 3 minutes - the longer the leave-in time, the more the actives can penetrate the hair fibre. Rinse thoroughly with cool water - cool water seals the cuticle and adds shine. Use daily for best results. The clinical improvements in thickness and elasticity are based on consistent daily use of the full system.

Why MASC Recommends This

The Fortifying Conditioner earns its place as more than just the second step in a wash routine - it's where the clinically tested strengthening system actually completes itself. The shampoo starts the work; the conditioner locks it in, adds the detangling and elasticity benefits, and ensures hair comes out of the shower looking fuller and feeling more resilient rather than just cleaner. The pea sprout, basil root, and rice protein trio running through both products means every wash is a consistent, reinforcing treatment rather than just a clean. If you're dealing with fine or thinning hair and want a daily routine that actively addresses it - without switching to a medicated or specialty product - this system is a well-tested, practical answer. Use both every day and give it four to six weeks to see the cumulative benefit.
