Anyone with bleached, highlighted, or all-over lightened blonde hair that has become porous, tangled, or rough from the lightening process. It works for any experience level since there's no mixing or professional application step, just a rinse-out mask after shampooing. It's not intended for hair that hasn't been chemically lightened, since the bond-repair action is built around the specific kind of damage bleach causes.

Because it's discontinued, it's really a fit for someone restocking a product they already use rather than someone starting a new routine, since it may not be restocked once current inventory sells out.

The reason to reach for this over a plain conditioning mask is the bonding action aimed at hair that's already been through bleach — rather than just smoothing the surface, it's meant to help re-link some of the internal structure lightening breaks down, which is why Schwarzkopf calls it "restore" rather than "condition." If your hair is fried from highlights or balayage and snaps or tangles more than it used to, that's the specific problem this mask targets, not general dryness.

Shampoo first, then towel-dry so hair is damp rather than soaking. Apply the mask through mid-lengths and ends — usually the most damaged part of lightened hair — and leave it in for 5 to 10 minutes. Rinse thoroughly. It's designed as a once- or twice-weekly treatment step, not a daily conditioner.

• Bond-repair action is targeted at bleach damage specifically, not a generic conditioning claim
• Short 5-10 minute treatment time fits into a normal wash
• No mixing or professional tools needed

• Discontinued, so remaining inventory is finite and may not be restocked
• Built for lightened/blonde hair specifically, so it's the wrong pick if your hair isn't chemically lightened
• Published ingredient lists for it disagree across retailers, so the exact formula can't be pinned down precisely
