Leave-In Hair Treatment | Now With MSM

Beautiful hair deserves more than a temporary fix.

Rather than relying on silicones or wax-heavy fillers, Mermaid Milk combines hair-compatible butters, lightweight oils, conditioning agents, and now MSM to help soften, smooth, hydrate, and improve manageability.

Formulated for curls, waves, and even straight hair that craves hydration, flexibility, and softness without a heavy, greasy feel.

Cupuaçu

(pronounced: koo-pah-SOO)

Sourced from the Amazon rainforest, Cupuaçu butter is prized for its rich emollient properties and ability to help soften and condition dry hair.

In hair care, Cupuaçu:

• Helps improve softness and flexibility

• Supports smoother, more manageable curls

• Helps reduce the feeling of dryness

• Provides rich conditioning through its natural fatty acid composition

This butter is a cornerstone of the formula—not a decorative ingredient.

NEW! Why We Added MSM

Methylsulfonylmethane (MSM) is an organic sulfur compound that has attracted attention in both skincare and hair care.

Sulfur is naturally present in keratin, the structural protein that makes up much of our hair.

We added MSM because we wanted to explore a sulfur-containing ingredient alongside our already nourishing blend of butters, oils, and conditioning agents.

What makes MSM interesting?

• Sulfur is an important component of hair's natural keratin structure.

• MSM is a source of organic sulfur.

• MSM has been studied for its potential antioxidant and anti-inflammatory properties, primarily in other applications.

• It offers an interesting addition to our ingredient-focused hair-care philosophy.
