Peter Thomas Roth Mega-Rich Nourishing Shampoo — Biotin B-7 & Pro-Vitamin B5, Lightweight Vitamin-Enriched Cleanse

Pete­r Thomas Roth Mega-Rich™ Nourishing Shampoo is a vitamin-enriched cleansing formula designed to gently remove buildup while helping hair appear stronger, shinier, and more nourished.

This shampoo blends a Biotin B-7 Complex with Vitamin E and Pro-Vitamin B5 to cleanse and condition in one step. The lightweight, rinse-away formula targets surface impurities without over-drying, leaving hair manageable and visibly healthier-looking. It’s crafted for routine use and pairs well with leave-in conditioners and styling products for fuller-looking results.

How does this shampoo support hair strength and reduce breakage?

The formula supplies hair with vitamin-rich ingredients meant to fortify strands and improve resilience to everyday wear. While no product can guarantee prevention of breakage, the combination of Biotin B-7 Complex and Pro-Vitamin B5 helps condition the hair shaft and reduce friction during washing and styling.

• Biotin B-7 Complex to help improve the appearance of hair strength.
• Pro-Vitamin B5 penetrates to condition without weighing hair down.
• Gentle surfactants cleanse while minimizing roughness on the hair cuticle.

Will this shampoo add shine and body to flat or dull hair?

Yes — the vitamin pairing in this shampoo works to smooth the hair surface for increased light reflection and a shinier finish. Added conditioning agents lift and separate strands for a perception of greater volume and movement.

• Vitamin E helps enhance surface smoothness for improved shine.
• Lightweight conditioning supports fuller-looking body without residue.
• Rinseable formula reduces buildup that can weigh hair down.

How should I use it in my haircare routine for best results?

Use on wet hair, lather, and rinse thoroughly; repeat if your hair is very oily or product-heavy. Follow with a conditioner or mask targeted to your hair type to lock in moisture and manageability. Incorporate it into a regular routine two to three times per week or as needed based on hair texture and styling frequency.

• Apply to thoroughly wet hair, massage into scalp and through lengths, rinse.
• Pair with a complementary conditioner or weekly treatment for deep nourishment.
• Adjust frequency according to hair oiliness and styling product use.

Is this safe for color-treated or chemically processed hair?

The gentle cleansing base and conditioning vitamins are formulated to be compatible with many color and chemical services, helping maintain manageability and shine. For best results, combine with a color-safe conditioner or treatment to protect pigment and reduce fading.

• Formulated to avoid harsh stripping of moisture common with stronger detergents.
• Works well as part of a color-care regimen when paired with color-preserving conditioners.
• Monitor hair response after chemical processes and adjust usage frequency as needed.

Who is this for: Ideal for people seeking an everyday vitamin-enriched shampoo that cleanses without drying, especially those wanting visibly stronger-looking, shinier, more nourished hair. It suits a variety of hair textures from fine to medium and is helpful for anyone using styling products or color treatments who wants a gentle, performance-driven cleanse that supports manageability and healthy-looking finish.
