This conditioner was formulated for blonde hair that's been chemically lightened or color-treated — the 'restore' in the name refers to conditioning after a bleaching or blonding service, not general daily conditioning for any hair color. It's a consumer-usable rinse-out conditioner, not a professional-mix-only product, so it can be used at home after a salon blonding service or alongside at-home toning products by anyone whose hair has become porous or brittle from lightening.

The specific reason to use this over a general conditioner is the hydrolyzed keratin system: bleaching strips part of the hair's natural keratin structure and roughs up the cuticle, and the keratin derivatives here are meant to temporarily patch that surface damage and smooth the cuticle down, which is what drives the detangling and shine benefit rather than a generic conditioning claim.

After shampooing, work the conditioner evenly through towel-dried, blonde or lightened hair. Leave it in for two to five minutes, then rinse thoroughly with warm water.

Pros:

• Hydrolyzed keratin and cocodimonium hydroxypropyl hydrolyzed keratin specifically target gaps in bleach-damaged cuticle, a real mechanism for reducing breakage on over-processed blonde hair
• Marula seed oil and cetyl palmitate add slip, helping with detangling — a common pain point on porous, brittle lightened hair
• Formulated specifically for blonde/lightened hair rather than as a general-purpose conditioner

Cons:

• It's discontinued, so remaining stock is finite and can't be reliably repurchased once current supply runs out
• Contains a silicone (dimethicone) and fragrance allergen components (citronellol, limonene, benzyl alcohol), worth noting for anyone avoiding those ingredients
• As a treatment aimed specifically at chemically lightened hair, it isn't designed to address concerns unrelated to blonde/lightening damage, such as curl definition or scalp issues
