How Long Does it Take To Grow Long Hair?

Depends on what kind of hair we're talking about. You'll have stubble in a day or two. Head hair will take a month or so to grow back out to a short length, and most likely years to grow out long. For body hair, it'll be undetectable that it was ever shaved in three to four weeks.

Hair usually grows approximately 6 inches a year, so in a week, it would be about an 8th of an inch, a half inch in a month and 6 inches in a year. Other variables would also be that hair grows more in the summer than the winter in the colder regions.

A few things that you can do to ensure that your hair follicle remains healthy and your hair is undamaged so it grows the quickest it can, are:

1. Take an inexpensive daily multi vitamin such as ‘ One-A-Day’ or even ‘Flintstones.’ Your hair likes zinc and biotin and both of the above mentioned vitamins contain ample amounts of these. Don’t waste your hard earned money on ‘Super Vitamins.’ Your body only requires so many vitamins per day and simply discharges the excess. You can’t put twenty gallons in a ten gallon tank. In some instances, over dosing on supplements can actually be fatal.
2. Do not brush your hair. With every stroke you damage your hair more. Brush only as much as you need to style your hair, then stop.
3. Buy a good quality brush or comb without a sharp plastic or metal ridges. This is one of the common factors leading to split ends. as is over brushing.
4. Don’t be penny foolish. Buy good quality salon products. The chemicals used in many if not most over the counter shampoos and conditioners, contain very harsh ingredients such as ‘ammonuim laurel sulfate’ which can actually dry your hair out, and cause breakage and split ends. Even worse, many contain a form of silicon, and that can be very bad for your hair.
5. Don’t consist your hair with tight bands, hats, braids and the like. These also lead to split ends and hair breakage.
