Mon Platin Koo Koo Keratin Treatment Effect is a three-phase leave-in spray that you shake to activate, apply to damp hair and blow-dry after five minutes, for smoother, softer, shinier hair without a full salon smoothing service.

The bottle holds three separate layers that mix when shaken, forming one active complex. Mon Platin built it around keratin for a smoothing effect, peptides to strengthen the hair and help with the look of split ends, and hyaluronic acid for shine and a soft, flexible feel. There is nothing to rinse out, and the brand says it reduces frizz from the first use.

Because it is a quick leave-in step rather than a chemical straightening treatment, it fits into a regular wash and blow-dry routine at home or in the salon. Mon Platin recommends it for every hair type, including natural or lightened blonde, coloured, chemically straightened, curly and untreated hair.

To use, wash the hair, shake the bottle until the colour is uniform, spray about 10 pumps onto damp hair, comb through, wait 5 minutes and blow-dry.

Size: 6.8 oz (200 ml).
