Irish entrepreneur James Murphy has sold Viviscal - his hair restoration brand to the owners of Arm & Hammer toothpaste, Church & Dwight in a deal reported to be worth €150m.
The Galway-based businessman's hair products are sold in 25,000 retail outlets across the US - it also sells directly through its online store.
Its range, which are aimed at both male and female customers, claim to offer "thicker, fuller looking hair" - by using a mix of proteins, zinc and other supplements to, "specifically nourish hair follicles to help maintain healthy hair."

It is 90% owned by Mr Murphy - and the brand has secured a host of celebrity endorsements from the likes of Jennifer Aniston, Reese Witherspoon, Gwyneth Paltrow, and Miley Cyrus.
Talking to People Magazine last year, Ms Aniston said, "I’ve got a healthy bag of vitamins I take three times a day, like Viviscal and your basic omegas and vitamin C," while Gwyneth Paltrow told Vogue, "It beyond works. I want to buy stock in that company."
Its range of products includes shampoos, conditioners and supplement pills.
The remaining 10% of the firm is controlled by a holding company called Lifes2Good.
The Irish Times states that BDO Development Capital Fund invested €5m in the firm during 2015 - while Mr Murphy maintained control of the firm.
Lifes2Good's other interests include dental products and supplements for pets.
