Spells that attempt to automatically lengthen your hair, doesn't necessarily work. And even if you tried putting that first mixture into your hair, it would take forever to get the glitter out! Take care of your hair and it will grow naturally strong and beautiful. Try not to blow dry it, or put a lot of product in your hair, try not to dye your hair often, and let it go natural. Heat can damage your hair a lot, and so can products.
Not all 'product' is bad for hair. In fact, some is great for hair. Coconut oil, for example, is a wonderful oil for hair. There's a long list of natural products which can help keep gair healthy. There is, of course, a much monger list of things to avoid and there are many controversial items.
But there are things you can find on your local grocer's shelves for a lot less than a tiny bottle of hair product with the exact same ingredient. Just do a bit of research.
Spells that can instantly make your hair longer are what we call on this site, "fluff." You cannot make your hair grow longer with spells, however, their are many natural products that are good for you hair like coconut oil, morrocan argon oil, etc... Let your hair grow naturally, and don't damage your hair, good-luck.
Yeah spells really dont do that for you. Spells cannot change your hair color or length, body shape or weight, and skin tone. Just take good care of your hair and cut it every so often to get off the dead hair, and make it grow faster.
I'm on my phone so I can't check the spells at this moment I'm afraid.
If these spells require you to make a shampoo of some kind, or say a chant while brushing your hair [and in both cases visualizing your hair longer] they could work. Not instantly, but it's worth a try [Though research the items in any shampoos first to make sure they're safe for your scalp and hair] a hair growth spell could work in a few ways [the items in the shampoo strengthens your scalp/hair, the chant and energy while casting speeds growth] just don't expect to wake up one morning with hair like Rapunzel. Perhaps measure your length on day one, then again a month later. The average rate of growth in a month is 1.25 centimetres. If the spell worked your hair would grow, say 2cm or more in that time. Give it a try, and see for yourself. Good luck to you.
