A sulfate-free solid shampoo bar with castor oil, keratin & silk amino acids. 60–80 washes per bar. Plastic-free, travel-ready, handcrafted in the USA. 4 oz

Salon-quality hair cleansing. Zero plastic. Lasts up to 80 washes.

Most shampoos are formulated around water and sulfates — effective at stripping, less effective at nourishing. The Nutrient Focus Solid Shampoo Bar is built differently: a concentrated, sulfate-free formula with castor oil, natural butters, keratin, silk amino acids, and botanical extracts that cleanse deeply while preserving the moisture your hair actually needs.

One 4 oz bar replaces 2–3 plastic shampoo bottles. 


What's Inside & Why It Matters

Castor Oil is rich in ricinoleic acid, which helps strengthen the hair shaft, support scalp circulation, and lock in moisture during cleansing — so hair comes out clean without feeling stripped.

Kokum Butter + Shea Butter provide a conditioning base that protects against dryness during the wash process, leaving hair soft and manageable without residue.

Keratin is the structural protein hair is made of. Including it in the formula helps smooth the cuticle, reduce frizz, and improve the overall resilience of the hair fiber over time.

Silk Amino Acids penetrate the hair cortex to bind moisture, improve elasticity, and reduce breakage — particularly beneficial for textured, dry, or chemically processed hair.

DL-Panthenol (Pro-Vitamin B5) attracts and holds moisture within the hair shaft, adding body and softness while supporting a smoother surface.

Botanical Extracts — Rosemary, Chamomile, Calendula, Lavender deliver antioxidant support, scalp-soothing properties, and gentle nourishment with every wash.
