A lot of people want to dye their hair with semi-permanent unnatural-color dye, such as Manic Panic, Special Effects, or Punky Color. Its actually quite a process and requires a lot of attention to detail or your hair will look/feel really bad, the color will not come out right, and itll fade instantly. This is, as far as I can tell, a definitive way to do it, from years of trial.
Step 1: Get Stuff
- basic hair dying tools: combs, hair clips, a tinting brush, plastic bowls, rubber gloves, petroleum jelly, tin foil (you can get precut tinfoil at the beauty supply store or just cut some everyday kitchen foil)
- bleach: BW2 or similar bleach powder, get two packets for short hair and a small bucket for longer hair. you really dont want to run out. peroxide developer (20 vol for light hair, 40 vol for dark hair) a small bottle (4oz) for v. short hair, a large bottle otherwise. its cheap stuff and you dont want to run out.
- toner: "blue lightening"/"platinum"/etc. for dying hair a blue, green, purple, etc shade. "light blonde", etc for dying hair an red, orange, yellow shade. They come in 2oz brown bottles. ask the salesperson to point you to it so you dont get the similarly looking hair dyes. they're often apart and near the bleach.
- hair dye: "special effects" is my favorite and seems to seep least and keep longest. however, "manic panic", or "punky color" is OK. get a couple similar shades to get a gradient effect. most hair can be done w/ a single bottle. if you have a lot of hair, get two shades to make sure you're covered. you'll also need some left over for touching up. some people use "kool aid", but i cant advise it I buy mine from the garment district, which also sells online. any reputable place will have a color swatch panel. If you happen to have some hair bits, say cause you just cut your hair or something, you can dye them to get a sense of how it will come out.
- other: j&j baby shampoo, hot oil treatment, an old/unwanted towel that you can use to dry your hair once its dyed
You can't get most of this stuff at a generic drug store, especially the bleach and toner... you must go to a beauty supply store!
