How long does it take to formulate a hair porosity product?

First prototypes typically take 4 to 8 weeks. Add 8 to 12 weeks for accelerated stability testing, which is generally required before retail launch and strongly recommended for FDA compliance. Complex bond-repair or multi-active porosity treatments may extend timelines further. Your cosmetic chemist will outline milestones in the project brief on the AJ Cosmo Labs app.
