Pink grapefruit extract and hair: what are the effects?

We all know and love grapefruit for its delicious pink flesh, not to mention the numerous health benefits it provides. The aqueous extract of grapefruit is used in dermo-cosmetics to stimulate cell renewal and refine the skin's texture. But what are its virtues when applied to hair?

An overview of pink grapefruit extract.

Grapefruit and pomelo are often confused. In fact, these two fruits belong to the genus Citrus, which includes the majority of citrus fruits. The grapefruit tree (Citrus maxima) produces enormous fruits, the grapefruits. However, this is not the one we consume in Europe! Indeed, it is the pomelo (Citrus paradisi) that is present in our supermarkets, whichis incorrectly called grapefruit.The confusion around the name of these two fruits has been ongoing for a long time and a change in nomenclature is not being considered.

The grapefruit, the ancestor of the pomelo, is consumed in the West Indies and Tahiti. Originating from China, it is sometimes sold in France under the name of Chinese pomelo.The pomelo, therefore commonly called grapefruit in France, is a fruit resulting from the natural crossbreeding between the grapefruit tree (Citrus maxima) and the sweet orange (Citrus sinensis). While the grapefruit comes from Southeast Asia, the pomelo is native to the Caribbean.

In dermo-cosmetics, thegrapefruit extract (which is in fact pomelo extract) is a powerful purifying and sanitising ally for the skin. Known by the I.N.C.I. name "Citrus Paradisi (Grapefruit) Fruit Extract", this aqueous extract is obtained by microwave extractionfrom whole fruits sourced from organic farming. No preservatives are added to the final product. The recommended percentage of this natural ingredient in a cosmetic formula is 3%.

Pink grapefruit extract can be incorporated into lotions and creams. Furthermore, this active ingredient can be added to numerous hair cleansing treatments such as shampoos and to serums promoting hair growth. Pink grapefruit extract is suitable for all hair types, particularly for hair prone to dandruff and requiring appropriate cleansing.
