some do, some don't, this website anyone can join. fluffs or fakes sometimes add spells that they add for fun or some other reason, if the spell does transformation or anything physical is not real, same with fantasy spells or spells about some kind of fantasy
Hair growth spells would be a gray area really. See, if the spell you used was some type of shampoo full of ingredients that will help the scalp, then I would say it could work. But if you just said a chant and went about your day, I'm gonna say no, it won't work. Magick works within the realm of nature and energies. Almost all spells are used to speed up things, like luck or love, instead of instant physical changes. Don't get discouraged if it doesn't instantly work though, spells take time.
I personally think magic can directly effect the physical world without the need of "ingredients", but such spells are extraordinarily difficult for any but the most powerful and experienced magic users. Don't be discouraged, if you need a spell it's easy enough to create your own as you need it. Just make sure to do some research, practice, and experiment. The ultimate catalyst of magic is your belief that it will work, always remember that. Faith does not guarantee success by itself, but it is always vital to success.
Really, if a hair growth spell was going to work, it would take more time than just a day to see results. Magick takes time, and while I don't know if the spell you tried is fluff or not, either way just have patience. The most any hair growth spell will do is possibly encourage it to grow at a slightly above average growth rate, which still isn't very fast. Give it time.
Also, I'm pretty sure there's natural oils and vitamins that also help hair growth if you can't find a spell that works or if you don't believe there is a spell that will help.
You can probably rinse your hair with self-made shampoo from herbs and flowers instead of harmful chemicals that damages and strips more than protects.
You can crush the herbs into powder and use baby oil for sleekness and softness and mixing the herbs with the oil and walala! Self made shampoo with the scent of natural flowers! I would recommend you use a pestle and a mortal to crush the herbs and flowers.
Look up herbology for witches
herbs can be used to make potions such as creams, shampoo, attractions, medicines and more.
Herbology will teach you which herb to use and for what purpose, and it will teach you which herbs are posionous.
Herbs are all around you as nature provides the ingredients. You need to know and gain knowlege of what herb to use.
It's usually safe to assume that spells or magic of any kind really won't work outside of what could naturally happen.
That being said, don't expect immediate results from most spells.
An example would be hair growth, if it was a legitimately useful spell it probably still won't happen over night.
