Here's the confusing part:
Alternate hot and cold water on your head in the shower. This stimulates your scalp and your hair will grow out faster =D
CLARIFICATION: When I said hot water, it's just the usual hot/warm water temperature you shower at! PLEASE DO NOT USE WATER THAT IS TOO HOT FOR YOUR SCALP, THAT WILL DRY OUT YOUR HAIR! the key is alternating between "cold" and "warm" temperatures. The temperature difference is what gonna stimulate hair growth.
Sorry for the confusion >_________________________< hope nobody has tried to run super hot water on their heads yet >___< Sorry sorry I'm so sorry!!! ahh!!!
Be back soon! =D
