Product Overview

Otter Co. presents a revolutionary approach to hair care with our Biotin & Onion Hair Growth Shampoo Bar. Designed to combat thinning hair and promote regrowth, this concentrated solid shampoo bar is packed with potent natural ingredients. Free from sulfates, parabens, and synthetic fragrances, it offers a gentle yet effective cleanse that supports scalp health and hair vitality. Each bar is equivalent to multiple bottles of liquid shampoo, reducing plastic waste and lasting longer. Perfect for daily use, it leaves hair feeling clean, soft, and voluminous.

Key Features and Benefits

  • Biotin-Infused: Biotin (Vitamin B7) strengthens hair strands, reduces breakage, and supports healthy growth.
  • Onion Extract: Rich in sulfur, onion extract nourishes hair follicles, improving blood circulation and promoting regrowth.
  • Keratin Protein: Reinforces hair structure, smoothing the cuticle for shinier, more resilient hair.
  • Rosemary Oil: Stimulates scalp circulation and has antioxidant properties that help prevent premature graying and thinning.
  • Apple Cider Vinegar: Balances scalp pH, clarifies buildup, and adds natural shine without stripping oils.
  • Vegan & Non-Toxic: No animal-derived ingredients, sulfates, silicones, or harsh chemicals. Safe for color-treated hair.
  • USA Made: Manufactured in the United States under strict quality controls.
  • Eco-Friendly: Zero-waste packaging and a concentrated formula that lasts 2-3 times longer than liquid shampoos.

How to Use

Wet your hair thoroughly. Rub the shampoo bar directly onto your scalp and hair, or lather between your hands and apply the foam. Massage gently for 1-2 minutes, focusing on the roots. Rinse well. For best results, follow with a conditioner bar or a light conditioner. Use 3-4 times per week or as needed. Store the bar in a dry place between uses to extend its life.

Who It Is For

This shampoo bar is ideal for women and men experiencing thinning hair, hair loss, or slow growth. It suits all hair types, including straight, wavy, curly, and coily textures. Gentle enough for sensitive scalps and safe for color-treated or chemically processed hair. Perfect for those seeking a natural, eco-friendly alternative to conventional shampoos.
