Blow drying your hair frequently can lead to dry, damaged hair and can fade your hair color more quickly. Hair that is chemically treated is especially prone to hair dryer damage, since the health of the hair has already been compromised. While air drying may take longer, the benefits are definitely worth it if you can find the time. Air drying is easy as it requires no special tools or time. You can multitask while waiting for your hair to dry; I typically apply my makeup as my hair is drying, for example. If you are still somewhat pressed for time, consider air drying your hair for most of the time and then finishing it with a blow dryer. If you do continue to blow dry your hair, be sure to apply a thermal protective spray before using any heating tools and consider keeping the hair dryer on a cooler setting.
Air drying is also more environmentally friendly and can save you money on your electricity bill (especially if you use multiple tools such as a blow dryer, straightener, and/or curling iron). According to a poll (summarized here: http://www.dailymail.co.uk/femail/article-2250701/How-time-really-spend-doing-hair-ladies-Answer-Ten-days-year.html), women spent about 15 minutes blow drying their hair each day and another 15 minutes styling the hair. For blow drying alone, that is 5475 minutes per year, or about 91 hours (3.8 days). In addition to saving money on electricity, you might also save money by making fewer visits to the salon by improving the health of your hair (less blow drying = fewer split ends = fewer trims).
I used to blow dry and straighten my hair every day when I was in high school, and the health of my hair definitely suffered from it. In college, I decided that I enjoyed having the extra 15-30 minutes of sleep or study time and typically resorted to air drying my hair on my way to class. Now, I usually shower at night and let my hair dry overnight in a satin head cap. Sometimes I end up with really nice waves in my hair when I wake up by doing it that way!
A simple way to save money each year is to trim your own hair. It’s actually very easy! Hair grows at a rate of about a half-inch per month and should be trimmed every 6-8 weeks depending on the growth and health of the hair. Trims should remove about a quarter of an inch of hair if the hair is being trimmed regularly. I have been trying to grow out my hair, so I avoid cutting it, but find it necessary to trim it every few weeks to remove the split ends and even the style out. If you are looking for a major cut or style change, I would suggest seeking the care of a salon specialist (perhaps you can save money by finding a friend who knows how to properly cut and style hair, or you can attempt to be more adventurous and try it out yourself). If you do decide to trim or cut your own hair, be sure to purchase a set of salon scissors; regular scissors can actually damage the hair. I found a pair of hair shears at Sally’s Beauty Supply for about $10. The average hair trim/cut costs about $20-$40, so the scissors have already more than paid for themselves. If you trim your hair every 6-8 weeks and switch to doing it yourself, you can save around $140-$280 each year. It may not sound like much, but can add up over a lifetime. It also removes the hassle of trying to fit an appointment into your schedule.

In my quest for better hair awhile ago, I stumbled across many websites suggesting sleeping on a satin pillowcase, so I figured that I would try it out. My hair is naturally prone to a lot of tangling, especially at night, so when I would wake up in the morning it would be a complete disaster. I invested in an inexpensive satin pillowcase (<$10) on Amazon and definitely noticed a difference in the look of my hair upon waking. Satin allows your hair to move more freely along the pillowcase and prevents rubbing; this can assist in preventing split ends and other damage. Cotton pillowcases (which are highly absorbent) can dry out your hair by robbing moisture from it at night, while satin helps your hair to retain moisture. Some websites also suggest that sleeping on satin is better for preventing facial wrinkles since cotton may cause crease marks. By sleeping on satin, you might improve the look of your hair and your skin!
