Portugal and Juventus star Cristiano Ronaldo has announced he plans to open a hair transplant center in the Spanish capital, to add to his ever-expanding list of business ventures.

Ronaldo is set to invest 25 million euros ($28 million) over the upcoming four years in Insparya, a ten-year-old Portuguese hair replacement center that has carried out over 35,000 hair transplants in Portugal.

The center is the newest in a long list of businesses the five-time Ballon d'Or winner has opened.

The first international branch of Inspraya is scheduled to open in mid-March in central Madrid.

Ronaldo's upcoming business plans for 2019 go beyond the hair transplant clinic, as he plans to open, again in Madrid, a new hotel with the Portuguese company Pestana, named Pestana CR7.

Pestana CR7, of which Ronald holds a 50 percent share, already has two branches in Portugal; one in Funchal, the capital of the Portuguese archipelago of Madeira, Ronaldo's home-town, and the other in the center of Lisbon.

A further two branches are scheduled to be opened this year; a 185-room Pestana CR7 in New York and a 164-room hotel in the Moroccan city of Marrakesh. In 2021, Ronaldo is set to invest 60 million euros in another branch of the hotel chain in Paris.

Since Dec. 2016, Ronaldo has also entered an alliance with Crunch Franchise, a United States-based chain of gyms, resulting in CR7 Crunch Fitness gyms that arrived in Spain with two branches to date, both in Madrid.

Not to be outdone by other stars and soccer players, Ronaldo has his own fashion line, including a perfume named Cristiano Ronaldo Fragrances which is a part of Eden Parfums.

Ronaldo also has a collection of men's and children's underwear in cooperation with the Danish company JBS Textile GROUP and a casual line named CR7 Denim.

The Portuguese star has taken his family into his business empire as his sister, Katia Aveiro, and mother, Dolores Aveiro, have opened a restaurant named Casa Aveiro.

Finally, Ronaldo has his own museum in Madeira where several of his trophies are displayed, including his five Ballon d'Or awards and five UEFA Champions Leagues titles.
