California Naturals Re:GRO combines naturally derived ingredients with targeted actives to support a healthier scalp environment and firmer-looking strands. Formulated without sulfates, silicones, parabens or phthalates, this 20 fl oz shampoo pairs strengthening nutrients like biotin with stimulant botanicals such as rosemary oil and caffeine to address signs of thinning and brittle hair. It's vegan, cruelty-free and B Corp–aligned, made for daily use and safe on color-treated hair.

How does this shampoo help when my hair feels thin or brittle?

Rather than promising instant regrowth, Re:GRO focuses on improving the scalp environment and reinforcing fragile hair to reduce breakage. Biotin supports keratin structure while botanical oils help repair and smooth damaged strands, so hair appears fuller and more resilient with routine use.

• Biotin strengthens hair fibers to reduce snap and split ends.
• Castor and argan oils add moisture and visible shine.
• Saw palmetto helps address DHT-related thinning pathways.
• Probiotics and zinc support a balanced scalp microbiome.

Will it stimulate my scalp and feel invigorating?

Yes — rosemary oil and caffeine are included to stimulate the scalp and encourage circulation, delivering a refreshing aromatic lift during washing. The scent profile blends rosemary, eucalyptus and basil for a natural, uplifting shower experience without synthetic fragrance overload.

• Rosemary oil for scalp stimulation and herbal aroma.
• Caffeine to energize the scalp surface and reduce thinning appearance.
• Natural scent from botanicals — no artificial perfumes.
• Sulfate-free lather that cleanses without stripping oils.

Is this product safe for color-treated or daily use?

Re:GRO is formulated for everyday use and gentle enough for color-treated hair because it avoids harsh sulfates and silicones. The blend focuses on nourishing and protecting hair integrity while maintaining scalp cleanliness, so regular use supports consistent improvement without excessive drying.

• Sulfate, paraben, silicone and phthalate free for gentle cleansing.
• Suitable for all hair types, including chemically treated hair.
• Non-toxic, vegan, and Leaping Bunny certified for ethical shoppers.
• Daily-friendly formulation to maintain scalp balance over time.

What visible results can I expect and how soon?

Individual responses vary, but routine use aims to reduce breakage and improve hair strength and scalp comfort. Over weeks to months, many users notice smoother strands, less flaking, and the appearance of fuller hair due to reduced shedding and stronger follicles.

• Reduced breakage from strengthened hair fibers.
• Improved scalp balance and fewer flakes.
• Enhanced shine and manageability from nourishing oils.
• Supportive blend for postpartum or stress-related thinning.

Who is this for: California Naturals Re:GRO Anti-Thinning Shampoo is intended for people noticing thinning, increased breakage, brittle strands or scalp imbalance who want a botanical, daily-use shampoo. It’s a practical choice for those seeking a clean, cruelty-free formula safe for color-treated hair and designed to support healthier-looking hair over time rather than an instant cure.
