Lot gone lionel messi explains decided dye hair blonde

I think there may be a few issues with the sentence you provided!

Firstly, "lot gone" doesn't make sense. Did you mean to say "a lot" or "lots"?

Secondly, Lionel Messi is a professional soccer player, not a hairstylist, so it's unlikely he would be explaining how to dye hair blonde.

Lastly, it's not common for people to dye their hair blonde, especially not Lionel Messi, who is known for his dark hair.

If you meant to ask a different question, please feel free to rephrase it, and I'll do my best to help!
