DUBLIN, Ireland — Perrigo Co. plc has begun shipping a store-brand version of Women’s Rogaine, a foam hair regrowth treatment.

Perrigo said it’s the first to market with an over-the-counter, private-label version of minoxidil topical aerosol foam 5%.

The product is packaged and marketed as a store brand or retailer “own label brand and provides consumers a high-quality, value alternative to Johnson & Johnson’s Women’s Rogaine 5% minoxidil foam product, according to Perrigo.

“This final approval and OTC launch is another example of introducing new store-brand products that are equivalent to the national brand while providing consumers with a lower cost alternative in the marketplace,” stated John Hendrickson, chief executive officer of Perrigo.

Women’s Rogaine minoxidil foam 5% is indicated to regrow hair on top of the scalp. The product’s annual sales for the 12 months ended in February totaled approximately $20 million, Perrigo reported.
