Well, I’d take off a couple to a few inches, because that always makes the hair nice and healthy. Do you know your hair dresser? If not, make sure you’re going to someone who has a handle on fine hair- I too have fine hair and I learned that lesson the hard way! Layers can be the greatest blessing to fine hair in the world, but they have to be done right. Done wrong, laywers will make your hair poof and lay flat all at the same time, in some magical hair dance of doom.
I would ask for some layers because they add quite a bit of versatility to hair. If your hair has a natural wave, some layers will make those waves. . . wavier (or some might even pop into loose curls). Also, on the off chance that you do decided to bust out the round brush and do a little styling, there’s a ton that can be done with layered hair. But if nothing else, layered hair will have a bit of movement throughout it, even if it’s just hanging down straight.
Have you ever considered darkening up the base? What your hairdresser would do is go one or two shades darker than what your hair is now. For thin hair, this adds a ton of dimension and the illusion thickness. Then, if you want to be wild, you can have your hair dresser work in a few natural looking highlights through the top. If you want them to look natural, don’t go more than a shade or two lighter than what your hair is now and make sure that your hair dresser weaves them in fairly loosely (so you don’t get big ol’ streaks). I’d go for a few highlights through the top, focusing particularly around your face. I think some darkening at the base, along with a few well placed highlights will give you an entirely new look that will look great.
As far as flat irons: are you using a ceramic one? For the love of goodness, please don’t mutilate your hair with a metal plated flat iron. If you are getting puffy mid day or frizzies at all, I suggest investing in a good flat iron. The top of the line is the Chi brand, but those can be costly. A nice ceramic plated iron can be bought at any beauty supply store for pretty cheap- a worthy investment at any price!
And frizz syrums are great, you just have to be VERY careful about the amount you use. I’m not fond of the ever touted “Frizz Ease” brand, but I do like BioSilk. In fact, I HIGHLY suggest a nice big bottle of Biosilk (hell, if you have too much you can use it on dry skin). Just make sure you use this stuff as sparringly as possible. Quite literally, a single drop rubbed between your palms will be more than enough to smooth out your hair for the entire day. This stuff is GREAT for when you’re being lazy and just pull your hair back into a pony- it takes care of all those pesky little hairs that stand up on the sides of your head.
If you really want to be wild, you can invest in some good quality shampoo and conditioner. Matrix Sleek Looks is a great way to combat the frizzy. Also, there’s any number of great volumizing shampoo sets that might interest you (I know my fine hair flattens out pretty quick).
Anyway, I hope this helped!
