Built on the LuminAlign System, it optimises light reflection while thermally aligning the hair fibre, on a glyoxylic acid base. The label states it is engineered for blonde and sensitive hair: a violet pigment lifts the reflect while the flat iron seals the realignment.\u003c\/p\u003e\n\u003cp\u003eSmooth Therapy carries the Formaldehyde Free seal and the V-Label International vegan certification on the label, the same as Reactive Pro Shampoo: a decisive claim for a UK client asking whether a straightening service uses formaldehyde.\u003c\/p\u003e\n\u003cp\u003eThe label caps ironing for this product at 160 to 190°C, never higher. That ceiling is lower than Piur London's other, higher-heat smoothing line, which is built for non-blonde, chemically resistant hair: the two lines share the same two-step logic, but Smooth Therapy exists specifically to protect the reflect that a higher heat range would compromise.\u003c\/p\u003e\n","brand":"Piur London","offers":[{"title":"Default Title","offer_id":48173222035696,"sku":"PIUR-RPR-PRO-SMOOTH-1000ML","price":251.28,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0787\/5647\/9216\/files\/PIUR-RPR-PRO-SMOOTH-1000ML.webp?v=1789180045","url":"https:\/\/piurlondon.com\/products\/reactive-pro-smooth-therapy","provider":"Piur Professional","version":"1.0","type":"link"}
