As far as hair treatments go, it sounds like a load of bull.

But a new product is available that is enough to make your hair stand on end â it’s made from bull’s semen.

An upmarket hairdresser’s has taken a leaf out of Cameron Diaz’s book â her character used sperm to style her hair in comedy There’s Something About Mary.

The 45-minute intense conditioning treatment uses thoroughbred semen from Aberdeen Angus bulls in a farm in Cheshire.

It is said to offer the ultimate shine for £55.

The hairdresser, Hari’s, in Knightsbridge, London, has combined the organically produced semen with the root of protein-rich plant katera.

The mixture is massaged into the client’s hair after it has been shampooed. Then the customer is put under a steamer so the treatment penetrates the hair. Finally, it is blow-dried.

Owner Hari Salem said he had tried hundreds of products, including wild New Zealand avocados and truffle oil.

‘I have been searching for an organic product with a lot of protein because that is what hair is made of and lacks when it is dry,’ he added. ‘All the best treatments are protein based. Synthetic treatments are good but they are heavy if you have fine hair and can make it look greasy. In the end, the bull’s sperm was the winner.

‘It really works. The semen is refrigerated before use and doesn’t smell. It leaves your hair looking wonderfully soft and thick.’

Mr Salem has no shortage of customers. ‘It will be an ongoing treatment as long as the bulls perform,’ he pledged.
