This shampoo made my hair shiny and smooth without causing back itch, but the medicinal smell and lack of thickening left me disappointed.

My Silky Hair Solution: No Itch, Just Shine

This shampoo and conditioner leaves my hair very shiny and smooth, and (of major importance) doesn't make my back itch. But it smells like an old-fashioned hospital, and I think the thickening comes from that third little bottle, and it made where I sprayed it feel rough, and, to me, unpleasant. If anything, my hair may be thinner than before.

I won't be buying it again.

Shampoo Basics & Tips

Understanding Shiny and Smooth Hair

Shiny, smooth hair often results from formulas containing silicones (e.g., dimethicone) or natural oils. These ingredients coat the hair cuticle, reflecting light and reducing frizz. However, buildup can occur, requiring occasional clarifying washes.

Preventing Scalp Irritation

The absence of back itch suggests a sulfate-free or hypoallergenic formula. Sulfates (SLS/SLES) strip natural oils, causing dryness and itching. Alternatives like coco-glucoside gently cleanse without irritation.

Clinical Scent in Hair Products

A "hospital-like" smell may stem from preservatives like phenoxyethanol or minimal fragrance additives. Brands targeting sensitive skin often avoid synthetic perfumes, which can trigger allergies.

Thickening Claims vs. Reality

Some shampoos use proteins (e.g., keratin) or volumizing agents (e.g., panthenol) to thicken hair. However, improper use or harsh ingredients (e.g., alcohol) can dry strands, leading to breakage and thinner-appearing hair over time.

Post-Use Texture Issues

A "rough" feeling after application might indicate product residue or incompatible ingredients (e.g., certain polymers). Always rinse thoroughly and avoid mixing silicone-based products with water-insoluble formulas.

I use purple shampoo for blonde hair, lathering well and preventing brassiness.

As a blonde, I use this purple shampoo weekly after clarifying shampoo because it lathers well with minimal product, and I massage it in for five minutes, leave it for ten minutes with a cap, then rinse with lukewarm water to prevent brassiness effectivel
