Sticky Residue on Scalp - Use Neutrogena Anti-Residue
Sticky residue on scalp is mostly caused by product build-up on oily hair type people. The residue is caused by styling products and conditioners and it get sticky because it get mixed with scalp sebum (excess natural oil produced by your scalp). Normally it won’t go away with regular shampoo and require deep cleansing.
A clarifying shampoo with high PH value should help to solve the problem and it should only be used once or twice a week followed by a light conditioner to restore the moisture back to hair.
There is a shampoo called Neutrogena Anti-Residue Shampoo. This shampoo should only be used once a week to remove residue or build-up caused by other hair care products like styling gels, conditioners, etc...
You should continue using your favorite shampoo and use Neutrogena Anti-Residue only to cleanse your scalp once a week.
Good Luck!
When I was pregnant I noticed a lot of changes with my hair and scalp. My scalp was oily and had build up that I could not seem to control with my regular shampoo. I did use this and it worked great for me. I used it about twice a week and it really helped. 
Hi Everyone, I have been so upset about my hair lately! I've never had a problem with my hair, and I use absolutely NO hair products. I simply wash, dry, and straiten it! But for the past month it's been a mess. Feels like I have shampoo left in it all the time. It's greasy and sticky, and simply impossible to manage. But what's funny is when I go out of town to my parent's house, it gets better. I thought maybe it could be hard water, but apparently no one in our area is having this problem. So it's just me!?! 
I moved a new apartment which had the same water source as my last apartment. I had no problem washing my hair at the old place. The very 1st night I took a shower in my new place I had what felt like grease film in my hair. I tried switching shampoos. Even used water at my moms house but it didn't change finally I was at my breaking point in my shower one morning and then it hit me oil spill. They use dawn dish soap to get the oil off the animals cause it strips oil off but leaves their natural oils they need to survive in wild. I jumped out of shower and ran to the kitchen and grabbed it ran back to shower and after I washed my hair with it the 1st time I could feel less of the oil goop in my hair so I washed it again and after 4 washes it was all gone. 
Thanks Megan!! - I can't wait to buy some dawn detergent and start using it asap. I can't take this anymore. I have no idea what the cause of this is.
