How does the Re:GRO set support a healthier scalp and hair strength?

The shampoo focuses on stimulating and cleansing the scalp while the conditioner reinforces strands to resist breakage. Together they work to create a more resilient hair environment through targeted botanicals and strengthening vitamins without harsh detergents.

• Caffeine provides a temporary energizing effect on the scalp surface.
• Biotin and nourishing oils strengthen fragile or brittle strands.
• Zinc and probiotics promote a balanced scalp microbiome.

Will this set work for colored or chemically treated hair?

Yes—both formulas are free of sulfates and silicones, which helps preserve color and reduce stripping. The conditioner is designed to add moisture and shine without leaving heavy residues.

• Safe for regular use on color-treated hair.
• Silicone-free conditioning keeps hair manageable without buildup.
• Formulated to minimize further damage to weakened strands.

What specific ingredients should I expect and why are they included?

The ingredient blend targets different aspects of thinning and weak hair: stimulation, strengthening and scalp balance. Key components were selected to combine immediate cosmetic benefits with ongoing support for healthier-looking hair.

• Biotin: supports hair shaft strength to reduce breakage.
• Caffeine: commonly used to invigorate the scalp area during cleansing.
• Saw palmetto and zinc: ingredients often used to help maintain a balanced scalp environment.

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

Use the shampoo to gently cleanse and massage the scalp, then follow with the conditioner focusing on mid-lengths to ends. Consistent, routine use can help maintain scalp balance and keep strands stronger over time.
