Formulated primarily for people wearing human hair extensions, wigs, or clip-ins who need a sulfate-free cleanse that won't loosen bonds or tape-ins; it's also marketed as suitable for natural hair. Sold through both professional salons and consumer retail, so no salon appointment is required to use it correctly, though extension-specific application care is worth following.

The reason to reach for this over a general shampoo is the Bellami co-development aimed squarely at extension and wig longevity: a sulfate-free wash that's less likely to weaken bonds or strip the hair the extensions are attached to over repeated washes.

• Apply, lather, and rinse.
• Avoid the extension installation/attachment point.
• Follow with Length Goals Conditioner (also avoiding the scalp and attachment point) and Length Goals Perfector.

Being sulfate-free is the real practical advantage for anyone with bonded, taped, or fusion extensions, since it's gentler on adhesives than a standard clarifying shampoo, and the added hydrolyzed wheat protein and conditioning polymers help offset the detangling difficulty extensions can add. On the downside, it contains several recognized fragrance allergens (linalool, hexyl cinnamal, benzyl salicylate, limonene) and synthetic colorants, and using it correctly on extensions requires a bit more care — avoiding the attachment point — than simply lathering and rinsing.
