After all the salt, sun and chlorine of summer, now is a good time to indulge in a hair-care treatment. Hair Spa Mon Reve at One Grand Tower in Mong Kok offers the Leonor Greyl treatment, customised for different hair types. The decor is minimalist, smart and modest. I'm shown into one of two VIP rooms where therapist Chloe Wong uses a microviewer to examine my hair and scalp. "Bad," is the verdict. Showing me a picture of my irritated scalp, she says it is sensitised, and points out a few flakes of skin. She recommends a desensitising treatment. Leonor Greyl uses concentrated botanical ingredients to nourish hair. The products are free of silicone, coal-tar, sodium laureth sulphate and parabens. The first step is an oil massage to prepare the hair for the treatment. Huile De Palme, formulated with palm oil, jojoba oil and botanical oils, is applied to smooth, detangle and repair. This is followed by a gentle scalp massage with a concoction that includes borage oil, Mimosa tenuiflora oil and other essential oils to stimulate blood circulation and cleanse the scalp. Next is a thorough application of Leonor Greyl Bain Traitant à la Propolis and Crème aux Fleurs. Wong then applies a jasmine-scented conditioning mask rich in amino acids, proteins and botanical oils, which aims at increasing hair flexibility as well as nourishing and regenerating all hair types. My hair is bundled up and placed under a steam helmet. A gentle rinse follows. The treatment ends with a refreshing massage. First, there's a stress-relieving shoulder rub using magnolia oil. Next, a vial of the brand's Complexe Énergisant is used to massage and activate microcirculation and oxygenate the tissues. A calming scalp massage culminates the hair spa experience. A stylist then blow-dries and styles your hair. My hair looks noticeably shinier and feels softer. Proof of the intense cleansing comes in the form of the "after" picture taken by the therapist's microviewer - it shows a marked reduction in the redness of the scalp, while the white flakes are conspicuously absent. More than a week later, my hair remains soft, my scalp feels less greasy and there are still no signs of dandruff. For continued results, a session every two to three weeks is recommended. The two-hour Leonor Greyl desensitising hair spa treatment costs HK$1,200 to HK$1,800 (depending on hair length).
