Always shampoo the hair and scalp twice. A euro sized amount of shampoo is more than enough. Create a lather in the hands and pop it into the scalp. Spend 30 seconds massaging the scalp, ignoring the hair. After the 30 seconds rinse well. 

Your second shampoo should be half the amount of product. Again, lathering into the hands and straight onto the scalp, this time you should get a much greater lather even when using half the amount of product. This time involve the ends of your hair very gently and leave for two minutes, bringing under the hairline. Rinse well. 

After your shampoo is rinsed, pop a euro sized amount of this product into the palm of you hands and rub together to activate the product. And like John Travolta in Grease, pull this through your scalp - make sure you're covering the scalp. Massage into the scalp. Then grab some hair conditioner/mask (if you have length in your hair) and pop it into the ends of your hair. Leave both there for 2-3 mins and rinse well.

Towel dry the hair & scalp gently and pop your Numinox all over the scalp or just into the areas on concern and massage in well. This will make the scalp blush - thats OK. You can also use this in between washes, morning and evening.
