Wholesale Castor Oil Shampoo

A castor oil shampoo bar is a solid cleanser formulated with Ricinus communis (castor) seed oil plus gentle, modern surfactants to cleanse hair and scalp without the bulky plastic bottle. This bar is designed to leave hair feeling clean, soft, and more manageable, while supporting the look of shine and healthy-looking hair in a concentrated, low-waste format.

In haircare, castor oil is widely used to help hair feel more moisturized, smoother, and shinier, especially on dry ends. It’s a richer oil that can support a more conditioned feel and help reduce the look of dryness or dullness. While many people associate castor oil with “hair growth,” shampoo is a rinse-off product—so it’s best to describe the benefits as conditioning, shine, and scalp-comfort support as part of a consistent routine.

Yes — this formula is especially friendly for hair that needs a softer feel after cleansing. It includes:

• Glycerin + Trehalose + Betaine (humectants that support a hydrated feel)
• Avocado butter, cocoa butter, shea butter (rich emollients for softness)
• Jojoba oil + Castor oil (oils that support slip and shine)
• Panthenol (Pro-Vitamin B5) (commonly used to support softness and smoothness)
• Hydrolyzed rice protein (helps hair feel stronger and more resilient to everyday styling)
  

This combination makes it a strong choice for customers who want a shampoo bar that doesn’t feel “stripping.”

This bar cleanses with Sodium Cocoyl Glutamate and Sodium Lauroyl Glutamate, which are gentle, amino-acid–based surfactants often used as alternatives to harsher cleansers like SLS/SLES. Many shoppers searching for a “sulfate-free shampoo bar” are specifically looking to avoid SLS and SLES, and this formula matches that preference.

This bar is a great fit for:

• Dry, frizzy, or coarse hair that wants softness and shine
• Curly and wavy hair looking for a gentler cleanse (often paired with conditioner)
• Normal hair that wants a nourishing, not-too-harsh shampoo bar
• Customers seeking a scalp-refreshing routine with botanical oils like tea tree and rosemary
• Shoppers who want travel-friendly, plastic-free haircare

For very fine hair that gets weighed down easily, recommend applying conditioner lightly and focusing shampoo mostly at the scalp.

For the best lather and performance:

1. Wet hair and the bar thoroughly.
2. Lather in hands first, or glide the bar over roots 2–4 times.
3. Massage the lather into the scalp for 30–60 seconds.
4. Rinse well and repeat if needed (especially with heavy styling products).
5. Follow with conditioner on mid-lengths and ends.

Pro tip: Tell customers to avoid “scrubbing the ends” with the bar—let the lather cleanse lengths as it rinses through.

This formula includes tea tree oil and rosemary oil, which many customers love for a fresh, “clean scalp” feeling. It can be a good option for people who want their scalp to feel more refreshed after washing. Since everyone’s scalp is different (especially if sensitive), it’s best practice to recommend a patch test and to avoid leaving lather on the scalp for extended periods if someone is reactive to essential oils.

A customer-friendly breakdown you can use for wholesale and retail education:

• Sodium Cocoyl Glutamate + Sodium Lauroyl Glutamate: gentle cleansing surfactants that create a creamy lather.
• Glycerin + Trehalose + Betaine: help hair feel less dry after cleansing and support softness.
• Avocado Butter, Cocoa Butter, Shea Butter: emollients that support a smoother feel and reduce “bar squeak.”
• Jojoba Oil + Castor Oil: add slip and shine; support a conditioned finish.
• Hydrolyzed Rice Protein: helps hair feel stronger and more resilient in daily styling.
• Panthenol (Pro-Vitamin B5): supports softness, smoothness, and manageability.
• Tea Tree Oil + Rosemary Oil: contribute to a fresh, invigorating wash experience.
• Tocopherol (Vitamin E): antioxidant that supports formula freshness and a nourished feel.

This formula is scented with tea tree and rosemary essential oils, which typically read as fresh, herbal, and spa-like. The scent is often described as clean and invigorating—great for morning showers and customers who like botanical aromas.

To extend bar life:

• Store on a well-draining soap dish
• Keep it out of standing water
• Let it dry fully between uses
• For travel, let it dry before putting it in a closed container

Dry storage is the difference between a bar that lasts and one that gets mushy.
