* Tanning Beds: This is the most common theory, as he has spoken about using them in the past.
* Spray Tans: This is another popular theory, as spray tanning has become increasingly common and can create a very even tan.
* Self-Tanner: This seems less likely given the consistently deep and even tan he maintains, but it's possible he uses self-tanner to touch up between salon visits or tanning bed sessions.
* Genetics: Hamilton himself has joked about having "a natural tan," but this is likely an exaggeration. He does have Irish ancestry, which can sometimes lead to more melanin production, but his tan is far beyond what most people of Irish descent achieve.
Ultimately, the exact details of Hamilton's tanning routine remain a secret. However, his iconic tan is a testament to his dedication to maintaining a certain look, and has become a part of his persona.
