A spokesperson for Hari's salon in London told CosmeticsDesign that, "we chose to use bull's semen in our latest 'Aberdeen Organic Hair' treatment after we discovered the rich proteins it contains creates a shine to the hair other treatments could not".
The treatment, which takes 45 minutes and involves a mixture of bulls semen and katira plant root extract being massaged into the hair, could well be the start of a trend within the cosmetics industry, with the protein element also thought to be beneficial in skin care formulas.
Indeed, the trend may well have started with Norwegian based company Maritex who stated that it was the main producer of Cod sperm for use in cosmetic products.
The company suggested that the sperm successfully binds water in body lotions and make-up, with the company said to have sold seven tons of processed cod sperm for use in cosmetics in 2002.
However, the motive behind the Hari's salon's decision to use the controversial ingredient was more scientific, with the protein in the semen thought to actively compliment the protein contained in hair molecules.
Hair manufacturers are constantly searching for pure forms of protein that match the hair protein quantities in order to create the most effective hair care treatment, and with the bull semen and Katira plant extract mix giving an almost instant and odourless finish, the treatment may be the start of big things to come.
However, with the semen having to be refrigerated in straws until use, it could be sometime until finished product manufacturers innovate ways in which to incorporate the ingredient into hair care products for the more daring consumer.
Costing £85.00 due to its exclusivity, the ingredient would no doubt be aimed at the premium hair care market and, being applied to clean hair and thought to penetrate the hair shaft, many consumers may be inclined to stick to more conventional hair care methods.
According to Mintel data, other unusual animal ingredients are being used in Asia and Latin America, with many companies incorporating placenta ingredients into skin care products.
Sofface cosmetics, based in China, has created a make up base that contains sheep placenta, whilst the Guangzhou Sisder Health & Beauty company has based an entire skin care body range using the same ingredient.
