The spray certainly helps unlock knots and tangles. A comb glides through the hair easier.
However, I find that after about an hour from application my daughter's hair is dry and brittle. Which is a let down considering the shampoo and conditioner are great products.
One way to combat this is to use an oil after the spray. Johnsons should consider revising their formula to allow the hair to remain moisturised. Perhaps a bit more glycerin or some olive oil.
Other than that it's detangling purpose is greatly served, particularly for ethnic hair.
