Even fine hair needs a moisture boost sometimes, especially when your hair is flat and colour treated. Hydrating Infusion serum blends perfectly with our top selling, volume building Essential Cleanse shampoo, to add an extra boost of weightless moisture. It's the perfect combination to restore flexibility and bounce to dry hair without losing the volume at the roots where you need it.

Suitable forfine, flat, oily root or dry ends.


Simply add a pump or two of the serum and blend it together with the shampoo in the palm of your hand before applying. Alternativly, you can add a few pumps of serum into your hair after washing and leave it in for blowdrying. 


Made from pure ingredients uniquely for Martinsson King in Grasse (France), our fragrance brings you a fresh essence that lingers lightly throughout the day, without interfering with your own scent.

Ger volym även åt tunna hårstrå, ”babyhår”


Ett bra schampo för mitt tunna hår, balsamet är väl ok. Ljuvlig doft. Kommer däremot inte överens med flaskan, de står ostadigt, ramlar ner från hyllan vid minsta stöt. En flaska gick sönder då den landade på golvet.


Passade tyvärr inte alls mitt hår. Håret känns strävt och smutsigt.


Bästa schampot jag har hittills testat blir inte skitig på det efter någon dag så man blir på de andra schamporna så bra schampo


Håret känns rent och fräscht länge.
Mycket nöjd!
