I have very thin hair and I found that this product was too heavy for me.
Even if I only used a small amount my hair would become greasy and need to be washed. It didn't really do anything for my hair in terms of repairing the ends - basically just a hit and miss.
I've had the same bottle for several years as you only need a little. Sometime I use when my hair is wet, other times on dry hair to tame the fluff. Too much product makes my hair greasy and flat. Disappointed that first ingredient is a silicone not oil but I guess this keeps the cost down. I'll repurchase when this bottle runs out.
