Hero ingredient — Keratin + silk + 18 amino acids.
What that benchmark led us to decide
Protein masks usually pick a side — repair or softness. This one runs a full keratin-silk-collagen stack with 18 amino acids and layered hyaluronic acid, so strands come out genuinely stronger and still soft. It screens 9.7, the highest on our shelf, and it's the bond-repair treatment we'd put in almost any damaged-hair routine — just once a week, not daily.
Rebuild what bleach and heat took out.
Damaged hair is, literally, hair that's lost protein. Roobliss LPT is a salon-grade pack that puts it back — a 50-protein complex with hydrolyzed keratin, silk and collagen, 18 free amino acids, and a multi-weight hyaluronic blend, worked deep into the strand in one treatment. Built for hair that bleach, color and heat have hollowed out.

Why damaged hair feels the way it does
Bleach, color and heat break down the keratin and lift the cuticle, leaving the strand porous and weak. That's the rough, stretchy, snap-prone, dull feeling — protein and moisture have leaked out, and ordinary conditioner only coats the surface.
Protein, in layers
Different protein sizes reach different depths — that's why a single-protein product only goes so far. This stacks them.
50-protein complex
Hydrolyzed keratin, silk, collagen, elastin and plant proteins in a range of weights, to reinforce the strand from the cortex out.
18 free amino acids
The building blocks proteins are made of — small enough to penetrate, helping the cuticle lie flat and hold moisture.
Hyaluronic + slip
A multi-weight hyaluronic blend with panthenol and conditioning agents rehydrates and detangles, so hair feels soft, not stiff.

Hair that's been worked hard
Three steps
Towel-dry
After shampooing, gently squeeze out excess water — protein absorbs better into damp, not dripping, hair.
Work through
Apply through mid-lengths and ends, comb through, and leave on a few minutes (longer for very damaged hair).
Rinse
Rinse thoroughly. Use 1–2× a week as upkeep, or as an intensive treatment after bleaching or coloring.

An honest note
Protein treatments rebuild and reinforce — they don't permanently "repair" a split end or undo damage for good; the benefit is real but builds with regular use. This formula is largely low-risk, and it does use silicones (dimethicone, amodimethicone, cyclopentasiloxane) for slip and fragrance for scent.
If your hair is protein-sensitive or feels stiff with frequent protein, space treatments out and balance with a moisture conditioner. The complete, risk-rated ingredient list is published right below this story.
Questions, answered
How often should I use it?
For most damaged hair, 1–2 times a week works well. After bleaching or coloring you can use it as a more intensive treatment, then settle into weekly upkeep.
Can protein make hair feel stiff?
It can if you're protein-sensitive or overdo it. If hair starts to feel stiff or straw-like, space treatments out and alternate with a moisture-focused conditioner — protein and moisture work best in balance.
Is it for colored or bleached hair?
Yes — that's exactly what it's built for. Bleaching and coloring strip protein, and this is designed to put it back and smooth the cuticle.
Does it have silicones?
Yes — dimethicone, amodimethicone and cyclopentasiloxane give the smooth slip and shine. They're rinse-off here and rated mid, not high. We list them in full below so you can decide.
