Peter Thomas Roth Mega-Rich Nourishing Shampoo — Vitamin-Enriched, Lightweight Shine & Body

Peter Thomas Roth Mega-Rich™ Nourishing Shampoo is a vitamin-enriched cleansing formula with Biotin (B-7), Vitamin E and Pro-Vitamin B5 that cleans hair while helping it look stronger, shinier and nourished.

This shampoo blends concentrated vitamins and conditioning agents into a sulfate-free-feel lather designed for everyday use. It aims to leave hair feeling clean without stripping natural oils, while adding visible body and shine. The formula is positioned for those who want a salon-ready finish from a clinical, results-minded brand.

How does this shampoo strengthen hair without weighing it down?

The Mega-Rich™ formula uses a Biotin B-7 Complex plus Pro-Vitamin B5 to support surface repair and manageability while maintaining lightness. Conditioning ingredients penetrate the hair fiber to help smooth and fortify, yet rinse clean for a non-greasy finish.

• Biotin B-7 Complex: supports hair surface resilience and texture improvement
• Pro-Vitamin B5: conditions hair from within for softer, more manageable strands
• Balanced cleansing agents: remove buildup without heavy residue

Will this shampoo improve shine and body?

Yes—this formula is engineered to boost reflectivity and lift for a healthy-looking finish. Lightweight conditioning and shine-enhancing vitamins work together to reduce dullness and increase natural movement.

• Vitamin E: helps enhance surface gloss and smoothness
• Formulation focus: designed to add body without stiffness
• Rinse-friendly: leaves hair flexible with visible sheen

How should I use it for best results?

Apply a small amount to wet hair, lather, and massage through the scalp and lengths, then rinse thoroughly. For more intensive conditioning, follow with a compatible conditioner or mask from the same line to lock in moisture and manageability.

• Use daily or as needed based on scalp and hair type
• Pair with Peter Thomas Roth conditioners for added nourishment
• Concentrate on roots for cleansing and lengths for conditioning

Is this suitable for colored or chemically treated hair?

The gentle, vitamin-forward cleansing is formulated to be compatible with many color and treatment routines, helping hair feel nourished after salon services. As with any treated hair, follow with a targeted conditioner or professional advice for best color retention.
