Prell Biotin & Rosemary Shampoo and Conditioner Set — Color-Safe 13.5 fl oz Bottles, Strengthens & Adds Volume

Prell Biotin & Rosemary Shampoo + Conditioner Set is a color-safe two-step system formulated to help strengthen fragile strands, add body, and refresh the scalp with rosemary botanicals.

This paired shampoo and conditioner combines biotin with rosemary extract to support the look and feel of fuller, healthier hair without harsh sulfates that can strip color. Each 13.5 fl oz bottle is designed for regular use on fine, limp, or damaged hair and for those who want to protect color-treated locks while improving manageability and shine.

How does this set help hair feel thicker?

The formula uses biotin, a nutrient commonly included in haircare to improve strand resilience and help hair appear fuller. Gentle cleansing and conditioning work together to reduce flatness at the roots and enhance natural body without weighing hair down.

• Biotin-enriched shampoo to support stronger-feeling strands
• Lightweight conditioner that detangles without heaviness
• Volume-supporting blend that lifts hair at the root

Will it protect my color-treated or highlighted hair?

Yes — the set is labeled color-safe and formulated to cleanse and condition without aggressive ingredients that fade dyes. It helps preserve tone while delivering moisture and softness, so colored hair looks brighter between salon visits.

• Sulfate-conscious cleansing to limit color stripping
• Conditioner provides hydration that seals the hair surface
• Suitable for regular use on dyed or highlighted hair

What benefits does rosemary provide for the scalp?

Rosemary extract is included to refresh the scalp and impart a clean, invigorated sensation after washing. It complements the strengthening effects of biotin and can help maintain a balanced, healthy-feeling scalp environment.

• Refreshing rosemary that calms and revitalizes the scalp
• Herbal aroma that leaves hair smelling fresh
• Supports comfortable scalp sensing after cleansing

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

Use the shampoo to gently cleanse damp hair, massaging into roots and rinsing thoroughly. Follow with conditioner from mid-lengths to ends, leave for a minute or two, then rinse to help detangle and impart moisture without flattening fine hair.

• Apply shampoo to wet hair, lather, rinse, repeat if desired
• Work conditioner through ends; avoid heavy application at roots
• Use regularly for ongoing strength and volume support

Who is this for: This duo is aimed at people with fine, limp, or chemically treated hair who want a gentle, color-safe routine that improves the appearance of thickness and strengthens fragile strands. It's a practical choice for anyone seeking lightweight hydration, scalp refreshment, and everyday manageability without risking color fade.
