Rthirtyone Ingredient Guide & Product Safety

Understanding what is in a hair-care product can help you make more informed choices. This guide explains ingredients found across selected Rthirtyone formulas. Always check the ingredient list on the individual product page and packaging, because formulas can differ.

Aloe vera

Aloe vera is commonly used in hair and scalp products for its lightweight, water-based conditioning properties. It can help formulas feel soothing and moisturizing, but individual responses vary.

Apple cider vinegar

Apple cider vinegar is used in some hair-care formulas to support a clean-feeling scalp and improve the feel of product buildup. The effect depends on the concentration and complete formulation.

Vegetable glycerin

Glycerin is a humectant that helps attract and retain moisture within a formula. Its performance can vary with the product, hair type and surrounding humidity.

MSM

Methylsulfonylmethane, commonly called MSM, is included in some topical hair-care formulas. Ingredient research should not be interpreted as proof that a finished Rthirtyone product regrows hair or treats a medical condition.

Peppermint, rosemary, lemongrass and capsicum

These botanical ingredients are often included for their sensory, aromatic and scalp-care properties. Essential oils and botanical extracts may irritate sensitive skin, so follow product directions and patch-test before broader use.

Lemon

Lemon-derived ingredients may be used for fragrance or formulation purposes. Avoid contact with the eyes and discontinue use if irritation develops.

Potassium sorbate and xanthan gum

Potassium sorbate helps protect some water-based formulas from spoilage. Xanthan gum helps create a stable, usable product texture.

Patch testing and safe use

Apply a small amount to a limited area and wait 24 hours before broader use. Do not apply to broken or irritated skin. Stop use if burning, rash, swelling or persistent irritation occurs. Seek medical advice for a serious reaction or ongoing scalp condition.

About ingredient research

An ingredient may have published research without the finished product itself being clinically tested. Ingredient evidence does not automatically establish that a complete formula produces the same result. Rthirtyone product descriptions should be read as cosmetic hair-care information, not medical advice.
