What are Silk Amino Acids?

“Hydrolyzed silk” can include a broader molecular-weight range (some fractions feel richer/film-forming). “Silk amino acids” typically emphasize low-MW peptides/free AAs for a featherlight, highly soluble finish, great for fine hair and lightweight serums.

They create a micro-thin conditioning layer that boosts slip and combability, helps reduce breakage, and adds soft gloss. Hair retains a natural bounce instead of feeling coated—ideal for fine or easily weighed-down hair.

Yes. They enhance slip & clumping, reduce frizz, and support springy definition. Pair with BTMS/cationic conditioners and humectants (panthenol, glycerin) to keep curls hydrated yet lightweight.

On skin, silk amino acids act as humectant/film-formers, leaving a silky, non-tacky finish. They help reduce the feel of tightness, improve surface smoothness, and layer well under emollients and occlusives.

They’re designed to be light and rinseable. Buildup is uncommon at normal levels. If you layer many rich stylers, use an occasional gentle clarify.

Yes. By improving wet/dry combing and reducing friction, they can lower breakage, so color looks shinier and hair feels more resilient. They don’t strip dye.

- Hair: Behentrimonium Methosulfate (BTMS) or cetrimonium chloride for slip, panthenol for hydration/shine, rice/oat protein for airy body, camellia/jojoba oils for lightweight softness.
- Skin: glycerin, hyaluronic acid, niacinamide, squalane, vitamin E for balanced hydration + smooth feel.

They can temporarily smooth and bind frayed ends to reduce frizz/snagging, but they don’t permanently fuse splits. Combine with regular trims and protective styling.

- Silk AAs: lightest feel, excellent slip & shine.
- Keratin peptides: hair-like; feel more fortifying/strength-forward.
- Collagen peptides: cushiony film-forming for skin feel; less common in hair.

Many formulas blend for balanced softness + strength.
