At six weeks to two months, most hairdressers recommend. And if you are doing any dye or cut, that is not your usual, it should be done then too. To decide if you want to book someone, you may want to see them further in advance, see how they work, and their general ideas. And you may want to try several styles out then to decide, book them, or make an appointment elsewhere. But even if you think a trial many months out was perfect, your stylist may have done 600 special styles and everyday people since then. And even if you took pictures then, don't think that after all this time they will reproduce it perfectly. Your hair reflects your physical health. If you ha e dieted, been I'll, been on some meds, the texture, fineness of hairs, and the way it behaves when blown dry, or is set with heat, changes. So if you do it way ahead to book, do a dress rehearsal closer to the wedding.
I did two diff styles but one I did on my own. I actually did mine like four months early and that was purely because I had a formal event to go to so it felt right to try it for that. So if you’ve got any events in the months prior to your wedding it would be nice to use that as a trial too
I just did my hair trial (4 months out from wedding) and am so happy I did! My stylist did 3 different styles for me and I fell in love with an updo after thinking I would for sure go with a half up/half down style.
I was getting married right after tax season and work long hours, so I had mine at the end of december. I came in with 2 styles. Definitely do multiple even if you are in love with one picture. I'd say 2-3
