Peter Thomas Roth Mega-Rich Nourishing Shampoo — Vitamin-Enriched Strengthening, Lightweight Conditioning

Peter Thomas Roth Mega-Rich™ Nourishing Shampoo is a vitamin-enriched cleansing formula that helps strengthen hair, add shine and deliver weightless nourishment.

This shampoo combines a Biotin B-7 complex with Vitamin E and Pro-Vitamin B5 to cleanse while helping hair look healthier and more manageable. The formula focuses on strengthening strands to reduce breakage, adding body and shine, and providing light conditioning so hair feels soft without being weighed down. It’s designed for everyday use on hair types that want a nutrient boost during regular washing.

How does this shampoo help strengthen hair during routine washes?

Strength comes from targeted vitamins that support hair’s surface integrity and resilience. Biotin (B-7) and Pro-Vitamin B5 work together to help reinforce strands and improve manageability, reducing the look of split ends and breakage when used consistently.

• Biotin B-7 Complex helps support the hair shaft for greater tensile strength
• Pro-Vitamin B5 penetrates to condition without heavy residue
• Vitamin E adds antioxidant support for smoother-looking cuticles

What kind of shine and body can I expect after using it?

The shampoo cleanses while enhancing natural gloss and lift, leaving hair with noticeable shine and a fuller appearance. It’s formulated to boost surface reflection and tactile softness so hair appears livelier and easier to style.

• Lightweight conditioning maintains volume rather than flattening hair
• Formulation smooths cuticle irregularities to increase gloss
• Rinses clean to prevent dullness from product buildup

Will this product work for my hair type and daily routine?

Peter Thomas Roth Mega-Rich™ is suitable for many hair types that benefit from added vitamins and gentle conditioning — particularly normal, dry, or chemically treated hair. Its balanced cleansing and nourishment profile makes it a practical choice for regular use, helping hair look maintained between treatments.

• Safe for daily or regular washing routines
• Helpful for hair needing moisture without heaviness
• Compatible with most styling and color-care regimens

How should I incorporate this shampoo into my haircare regimen?

Use it as your primary cleansing step: apply to wet hair, massage into scalp and lengths, then rinse thoroughly. For best results, follow with a conditioner tailored to your hair’s moisture needs and use a weekly treatment when deeper repair or hydration is needed.

• Apply to wet hair, lather, and rinse completely
• Pair with a conditioner for additional softness and detangling
• Use a weekly mask if hair is especially dry or chemically processed

Who is this for: This shampoo is aimed at people seeking a daily cleansing product that also provides vitamin-rich support for hair strength, shine and lightweight conditioning. Ideal for those with normal to dry or chemically treated hair who want a salon-quality vitamin boost without heavy residues. If you need targeted repair for severe damage, consider pairing with intensive treatments in the Peter Thomas Roth haircare line.
