@abierose - If a product isn’t being washed out, then it can have its full effect on the hair. The “competition” between molecules doesn’t matter as much. No, I don’t really think ingredients benefit the follicle. Ingredients are more important for affecting the hair fibers.

@MsBG - Pre-wash products can work. I know the VO5 Hot Oil product I worked on actually affected hair even though it was applied before shampooing. This was because the cationic ingredient in the VO5 would react with the anionic surfactants in shampoo and provide additional conditioning. But mostly, I don’t think pre-wash products will have much impact that isn’t washed away.

Thank you Perry. Which of ingredients in the VO5 hot oil treatment would you say are the most effective, if you still remember that is

This has been a very useful and eye opening discussion. 

@Perry and other knowledgable formulators/cosmetic scientists, what are your thoughts on Pre-Wash/Pre-shampoo products. I have type 4 hair and I’ve used these for a while now and I am now questioning whether they are effective if they will only get washed off by a shampoo? Is it possible that if I put on a pre-wash leave on a day before I shampoo then shampoo the day after I would have just washed off the leave on?

I had no idea what Zolinones where and now I do. I’ve just liked your Facebook page
