I have heard complaints that dry shampoo doesn't work or some people say it makes their hair dirtier. I have found that if I spray the dry shampoo on my roots and then take my blowdryer (yes, with dry hair) and I know this sounds gross but "dry the grease out"... It really works.  

I use a Wet brush to brush the ends of my hair and then a boar brush to get nice, soft curls. The boar brush helps spread the natural oils from your hair to all the right places. 

I can't seem to go past 3 days of dirty hair if I try and wear my hair straight. I get the best dirty hair results with curled hair. You can curl your hair multiple days in a row, as long as you use a thermal protector! Not shampooing your hair for multiple days isn't always the healthiest option and it still does damage to your hair. You must make sure to use product every single time you add a hot tool to your hair! I use a combo of a hair wand and a couple days later a big barrel curling iron. 

I personally wear my hair up to bed because it is on the longer side and after a couple days of dirty curls, it can get tangly! I also recommend wearing your hair in a ponytail on the last day with some hair accessories or a bun. My personal favorite is a sock bun! 

Seriously. Don't give up! That same life motto goes for your hair, too. The more you do it, the easier it becomes.
