Donald Trump has been stealing headlines with his presidential run, but there's one question none of the debates have asked: What's with the hair?

His very particular color, cut and combing technique has raised questions since the real estate tycoon was first in the spotlight, inspiring #trumpyourcat hashtags and even TODAY Halloween costumes. But The Donald isn't shy about sharing his hair-care secrets.

Below, see some of the most hair-raising things he's had to say about his strand style.

1. “As everybody knows, but the haters and losers refuse to acknowledge, I do not wear a ‘wig.’ My hair may not be perfect, but it’s mine.” (Twitter)

2. "I would probably comb my hair back," Trump said of how he might change his hair if elected president. "Why? Because this thing is too hard to comb. I wouldn't have time, because if I were in the White House, I'd be working my ass off." (Des Moines Register)

3. “I’ve been called out by everybody for the ALS ice bucket challenge. Homer Simpson, Mike Tyson, Vince McMahon … I guess they want to see whether or not it’s my real hair, which it is.” (Trump YouTube channel)

5. "I get up, take a shower and wash my hair. Then I read the newspapers and watch the news on television, and slowly the hair dries. It takes about an hour. I don’t use the blow dryer. Once it’s dry I comb it. Once I have it the way I like it — even though nobody else likes it — I spray it and it’s good for the day." (Playboy)

6. "The reason my hair looks so neat all the time is because I don't have to deal with the elements. I live in the building where I work. I take an elevator from my bedroom to my office. The rest of the time, I'm either in my stretch limousine, my private jet, my helicopter, or my private club in Palm Beach Florida [...] If I happen to be outside, I'm probably on one of my golf courses, where I protect my hair from overexposure by wearing a golf hat." ("Trump: How to Get Rich")

7. "What's the difference between a wet raccoon and Donald J. Trump's hair? A wet raccoon doesn't have seven billion f---ing dollars in the bank." (Comedy Central Roast)

8. "I will also admit that I color my hair. Somehow the color never looks great, but what the hell, I just don't like gray hair." ("Trump: How to Get Rich")

9. "You can check it. It's actually my hair. It may not be beautiful, but it's my hair." (Ryan Seacrest Presents)

10. "I actually don't have a bad hairline. When you think about it, it's not bad. I mean, I get a lot of credit for comb-overs. But it's not really a comb-over. It's sort of a little bit forward and back." (Rolling Stone)
