It sounds as if your hair is limp and lank, either from excess product or from natural sebum production. The grease, be it natural or caused by products, is separating your hair in to sections. You have naturally very fine hair, and separation is a fairly common problem among people who have fine hair, as it is the first hair type to be affected by any kind of excess oil in the hair. My first piece of advice would be to try a special shampoo, such as Kebelo Clarifying Shampoo, that purifies the hair more than an ordinary shampoo. Clarifying Shampoo acts like an exfoliator for the hair and scalp, ridding it of excess styling products, environmental impurities, grease, sweat and dirt build-up. These are common causes of limp, lank hair that can separate, as you have described. If, after trying a deep-cleansing shampoo, you notice hair is becoming separated again within a day or two, it may be that you have naturally oily hair, that needs caring for with products tailored specifically to this hair type. Kebeloís award-winning Revitalising range is a prescriptive range of products, designed especially for fine hair that is naturally oily and limp. The Revitalising Shampoo has been formulated to remove excess oils from the hair and scalp, without stripping the hair or leaving it dry. The Revitalising Conditioner has been created to give an injection of moisture to hair and nourishing locks, but without adding any grease or weight to the hair, so it doesnít cause the separation problem you have described. As your hair is medium length, you may also benefit from the BONDAGE Weekly Colour Masque, which provides additional deep conditioning and repair to any damaged hair, which then boosts the hairís body and volume. If you notice your hair is still becoming greasy and separated, within the same day as washing it, take a look at the styling products you are using. If you are using any serums or finishing products, make sure they are specifically for very fine hair. If you wish to smooth your hair, oils should generally be avoided, as they are too heavy for fine hair, whereas smoothing creams are much more suitable.
