Schwarzkopf Professional Bonacure R-TWO Resetting Shampoo (sulphate & silicone-free), 250 ml

What it is and why people buy it

Schwarzkopf Professional Bonacure R-TWO Resetting Shampoo is a wash-day shampoo aimed at hair that feels over-processed or fragile. The idea, on paper, is to help “reset” stressed hair by building new bonds (the brand’s double bonding technology) while you cleanse—so it’s not just about removing product and dirt. It also claims to balance the pH level using a pH-optimised formula, with a vegan approach that is free from sulphates and silicones.

If your hair is prone to tangling, feels weaker after colouring/bleaching, or you notice more breakage during brushing, this kind of bond-focused, gentle-cleanse shampoo can be a sensible step. It may not magically erase damage overnight, but it’s the sort of shampoo that fits into a repair routine where you’re trying to improve manageability and strength over time.

The essentials (the stuff that matters)

This shampoo is designed for damaged, chemically or physically stressed hair. It’s positioned as a gentle cleanser rather than a stripping clarifier, with the brand stating it balances pH and supports resilience. There’s also a specific benefit claim in the description: it strengthens each hair fibre and is said to reduce breakage by up to 93% with every wash.

On the practical side, sulphate- and silicone-free formulas can suit people who find heavy or residue-forming silicones make hair feel coated, or who prefer a more lightweight finish. The vegan formula is another factor if that’s part of your buying criteria.

Worth noting: the “up to 93%” figure is a headline claim, and real-world results depend heavily on your hair type, how porous it is, and whether you’re using complementary products alongside it.

What you’ll notice day to day

If you’re choosing a bond-repair shampoo, you’re usually looking for a few specific improvements: less snagging when your hair is wet, hair that feels easier to detangle, and fewer moments where ends feel brittle.

In everyday use, this could look like washing, applying conditioner afterwards, and finding your hair combs through more smoothly rather than feeling stretchy or rough. It’s also framed as having “instant, long-lasting” results—so the hope is that you feel the difference after the first few washes, not just eventually.

Who it suits best

It makes sense if you have damaged hair from processing (like colouring or bleaching) or from physical stress, and you want a sulphate-free, silicone-free shampoo that supports bond-building and pH balancing.

It’s also a good fit if your routine includes other hair-care steps—like conditioner and treatments—because a single shampoo rarely does everything. Think of this as the cleanser that supports the rest of the repair plan.

When it might not be the best choice

It might not suit you if your hair is very fine and gets weighed down easily, because while the formula is silicone-free, it’s still a repair-oriented shampoo and your overall routine (conditioner, leave-in, styling) matters. Also, if you were expecting a deep-cleansing “reset” in the literal sense (for example, to remove heavy build-up), a gentler sulphate-free shampoo may not feel strong enough on its own.

Key things to check before you buy

Look closely at your goals and current routine. If you’re mainly trying to lift stubborn build-up from hard water, oils, or frequent styling products, you may need a different cleansing approach alongside (or instead of) this kind of bond-focused wash. If your priority is fragile, over-processed hair that needs gentler cleansing with pH support, it aligns well with that.

Also, remember that the description focuses on repair and resilience, not on styling performance. If you’re after a shampoo that also gives strong slip and a noticeable “finished” feel by itself, you’ll likely still need conditioner to get there.

Final verdict

Worth considering if your hair is stressed and you want a vegan, sulphate- and silicone-free shampoo that targets bond-building and pH balance, with a clear focus on strengthening and reducing breakage. It’s the kind of purchase that can fit neatly into a repair routine when you’re willing to use it consistently.

You may want to skip it if you need a strong clarifying cleanser for heavy build-up, or if you don’t plan to pair it with a conditioner/treatment—bond repair shampoos generally work best as part of a broader routine.

Mini FAQ

How does a bond-building shampoo differ from a standard repair shampoo?

Bond-building shampoos are formulated to support the repair of stressed bonds while you cleanse, rather than only conditioning the hair’s surface. In this case, the description highlights “double bonding” technology and pH balancing alongside gentle cleansing.

Is it suitable for colour-treated hair?

The product is aimed at chemically stressed hair, which often includes colour-processed hair. However, the description doesn’t explicitly state compatibility with all dyes or treatments, so it’s worth checking your hair-care requirements and patch testing if you’re sensitive.

Will it remove product build-up on its own?

The shampoo is presented as gentle and sulphate-free, so it may not be the strongest option for heavy build-up. If you have lots of residue, you might need a stronger cleansing step in your routine.

Is it really silicone-free?

Yes—based on the information provided, it is sulphate- and silicone-free.
