Description

EXAMPLE 1

[0221] The following composition according to the invention was prepared:

TABLE-US-00001 Composition (% AM) PEG-60 Hydrogenated 0.25 castor oil Carbomer 0.3 Polysorbate-21 0.5 L-menthol 0.3 Laureth-12 1 Sodium hyaluronate 0.01 Ethanol 25 Water Qs 100%

[0222] A study was done on 18 braided hair women aged 20-40 years, having their braids on for a minimum of 2 weeks. The composition was applied on scalp and braided hair at least 3 times during a period of 7 days.

[0223] The study shows that the product provided immediate and long-lasting relief of itchiness, dandruff and discomfort; pleasant and soothing sensation on the scalp. It also shows that braided hair and scalp are moisturized and nourished. The composition makes the braided hair texture soft.
