Can you believe there is a product named this? I was shocked. Problem: Hair is oily or greasy at the end of the day or you didn’t have time to shampoo this morning. Solution: Pssssst Instant Spray Shampoo. Specifically, it is a dry aerosol leave-in shampoo that is suppose to be used in between regular wet shampoos or for those times that you “don’t have time” to wash your hair.
What I personally use this for is for hot and humid days where I wake up in the morning and shower and dress as normal but after a day at work my roots start looking a little on the oily side (depending on the day or styling products that I’ve used). Pssst Hair Shampoo helps on those days as I can just spray a bit on the roots of my hair, let it dry, and then restyle it. I used this once when I was staying overnight in the hospital and was unable to shower right away the next morning, just wash up in the sink, etc.
The other use I have found for this product – it is helpful when you have over-applied detangler or any other oil-based substance to your hair. Instead of hopping back in the shower and re-shampooing, use Pssst Hair Shampoo instead – your time is worth something 
Its nice to see the uses of you shampoo. I advise all the people who use these natural shampoos to use cool not hot water to rinse your hair.
Additionally your water may have lots of chlorine and or heavy minerals. For shampooing and rinsing your hair add a small amount (a teaspoon of baking soda or a squirt of lemon juice) to the water, use a pitcher made of plastic, not metal. To soften it add just enough baking soda for the water to feel slippery between your fingers. Hope everybody can follow such simple tricks to safeguard their hair. Thank you!!
