That is simple, isn't it?
I have heard many friends and colleagues complaining about having to use hair styling or moisturing products, blow drying it every day and night, treatment it every week, wasting alot of their time so on and so forth... Yes, I totally get it. Laziness is also my part-time job. I can get totally lazy and not do anything but if I want nice looking manageable hair, then I'll do it but I do it the lazy & fast way! ^,^
First of all and also the most important for me is to invest in good hair tools such as a good hair dryer. I personally prefer a higher voltage one with multiple heat settings which I can blow dry my somewhat voluminous hair in the shortest time. I said 'somewhat' because I do not have thick hair. It is thick because I bleached and dyed it many times so the middle part to the ends are thick and super dry, while the area near the roots are thinner and flatter. You can read more about my hair at the About section.
Oh yes, I forgot to mention that the main reason for me to use a high voltage hair dryer with multiple heat settings is that I actually blow dry my hair in room temperature. Using a fan takes a long time to achieve an entirely dried hair and most probably would end up dry at the outside and wet underneath (most people do this). With a wet or damp scalp, you can easily get bacteria growing in there. So what your mummy or grandma have always said, "Do not sleep with wet hair" is actually correct because it is not good for your hair and your scalp.
With a high voltage dryer, you can blow dry your hair in a shorter amount of time because the strong wind from the dryer focuses at one area. It dries even faster if you switch between different heat settings back and forth. I usually like to use the medium high heat for near my roots area (virgin hair) and then switch to room temperature for the rest of my hair and scalp (room temperature will not cause much damage to your hair), making sure that the scalp is entirely dry first, then the hair. As much as the hair is important, the scalp is most precious to me. No good scalp, no good hair.
Always remember that. ^_~
