There has been speculation and discussion online about whether Mohamed Salah, the Egyptian footballer who plays for Liverpool FC, underwent a hair transplant. However, there hasn't been any official confirmation or statement from Salah or his representatives regarding this.

Fans have noted that his hairline appears fuller compared to earlier in his career, which has led to rumours about a potential hair transplant. It's not uncommon for public figures, including athletes, to undergo such procedures, but without official confirmation, it's purely speculative.

Hair transplants are a popular option for many people dealing with hair loss, and they involve transferring hair follicles from one part of the body (usually the back of the scalp) to the thinning or balding areas. The procedure has become more advanced and common in recent years, leading to natural-looking results.

From a technical standpoint we can say with absolute certainty that Salah has indeed undergone a hair transplant at the front of his hairline, and possibly at the crown region of his scalp, also. Salah's locks were visibly thinning last season, before he cut his hair short. 

Since Salah's return for the new season, his hairline, which was receding into Norwood 3 territory, appears to have been restored, as well as the hair at the crown region, which was visibly thinning last season. 

Such a procedure would have cost the football star in the region of £3,000-£8,000, depending on where he had the surgery done. 

A hairline hair transplant surgery is a cosmetic procedure designed to restore or improve the appearance of the hairline, particularly for those experiencing hair thinning or recession. 

A hairline hair transplant surgery involves relocating hair follicles from a donor area (usually the back or sides of the scalp) to the front of the head, where the hairline is thinning or receding. This procedure helps create a fuller, more youthful hairline.
