Color-treated hair experiencing breakage, weakened strands, or split ends. The brand markets it as suitable for all hair types. It's a consumer retail conditioner, easy for any experience level, and gives its best measured results when paired with the matching Strengthening Shampoo.

The strength claims here are specifically tied to using this conditioner as part of a two-step system with the Strengthening Shampoo — the BondLock and arginine combination is what's actually been tested for breakage reduction, so the differentiator is a measured system result on color-damaged hair rather than a stand-alone deep-conditioning treatment.

• Shampoo first with I Want Strength (Strengthening) Shampoo.
• Apply conditioner through lengths and ends.
• Distribute with a wide-tooth comb for even coverage.
• Rinse thoroughly, avoiding contact with eyes.

• Pro: PETA-certified cruelty-free, with bottles made from up to 95% post-consumer recycled plastic.
• Pro: BondLock Technology plus arginine is tested to reduce combing breakage on color-damaged hair by up to 73% when paired with the matching shampoo.
• Pro: Color-safe, usable across hair types.
• Con: The 73% breakage-reduction figure is a paired-product result (shampoo + conditioner vs. a non-conditioning shampoo), not a stand-alone claim for this conditioner alone.
• Con: Contains dimethicone (silicone), so it isn't suited to a strict silicone-free/"low-poo" hair routine.
