California Naturals Re:GRO Anti-Thinning Shampoo & Conditioner Set — Biotin & Caffeine, Sulfate-Free 20 fl oz

Re:GRO Anti-Thinning Shampoo & Conditioner Set is a two-step haircare duo formulated with biotin, caffeine, rosemary oil and nourishing oils to support stronger, fuller-looking hair and a healthier scalp.

This duo from California Naturals combines a sulfate-free shampoo and a conditioning treatment designed to work together: the shampoo cleanses while delivering follicle-supporting actives and the conditioner hydrates strands and helps reduce breakage. The formulas blend botanical actives, zinc, probiotics and plant oils to target common causes of thinning hair like brittle strands and scalp imbalance, while remaining vegan and free of sulfates, parabens, silicones and phthalates.

How does this set help reduce breakage and strengthen strands?

The Re:GRO pair uses biotin and nourishing oils to fortify fragile hair and improve elasticity, so strands resist snapping during brushing and styling. Regular use helps replenish moisture and supports a smoother, more resilient hair surface without weighing hair down.

• Biotin strengthens keratin structure to reduce split ends.
• Argan and castor oils add shine and repair damage.
• Conditioner restores hydration for smoother, easier-to-manage hair.
• Sulfate- and silicone-free formulas keep hair light and breathable.

Will this set help a dry or irritated scalp?

The formulas include rosemary oil, zinc and probiotics to soothe and balance scalp microbiome conditions that can contribute to flaking and discomfort. Gentle surfactants clean without stripping, while botanical actives deliver calming, moisture-retaining benefits.

• Rosemary oil supports scalp circulation and a refreshed feel.
• Zinc helps regulate excess oil and soothe irritation.
• Probiotics promote a healthier scalp environment.
• Natural rosemary-eucalyptus-basil scent avoids heavy synthetic fragrances.

What ingredients target thinning and encourage fuller-looking hair?

This set combines caffeine, saw palmetto and botanical extracts with vitamins and minerals aimed at improving the appearance of density. Rather than a single miracle ingredient, the formulas layer several supportive actives to nourish follicles and strengthen emerging hairs.

• Caffeine energizes the scalp to improve the look of density.
• Saw palmetto is included as a botanical that supports hormone-related thinning concerns.
• Zinc and B-complex nutrients help maintain healthy hair growth cycles.
• Plant oils and conditioning agents improve shine and manageability.

How should I use the Re:GRO shampoo and conditioner for best results?

Use the shampoo to cleanse and massage the scalp, rinsing thoroughly, then follow with conditioner from mid-lengths to ends to detangle and seal hydration; leave the conditioner on for one to three minutes before rinsing. Consistent use as part of your routine gives the scalp and hair the sustained nutrients they need to look healthier over time.

• Wet hair, apply shampoo and massage into the scalp for 60–90 seconds.
• Rinse and apply conditioner focusing on lengths and ends.
• Leave conditioner for 1–3 minutes, then rinse for best shine and softness.
• Safe for daily use and color-treated hair.
