you cant really speed hair growth, though you can do stuff that does help with healthy growth. check your diet, lots of water and healthy vegies, protiens is a must. I used to take biotian, its great it helps, will start it again, msn is good as well, helps with hair growth and stregth.
ive got a scalp stimulater hair growth oil mixture, wich is great i love it, it really works.
how ever, nothing works over night, hair grows in stages, with the diet, biotian and msn, you should give 6 weeks to work. though with the oil mixture, you can notice it sooner

my hair: 3c, high porosity, high density and coarse hair (i think i finally figured that all out)
my hair loves conditioner only styling!
my hair goal length is bra strap length when curly.

I also blog about my hair journey, please feel free to read and comment/ask questions
