A: Hi Jenna, Great question! We recommend using Function of Beauty at Target products within 2 years from the manufacture date.

A: Hi AC, We love someone who knows what they want! We encourage variety in your #hairgoal booster shot selection, but if you'd like to put 3 of the same one in, go for it. At the end of the day nobody knows your hair, and what it needs, better than you do.

A: Hi Olive, Thanks so much for your interest in our heat protectant goal. This goal protects your hair from the elements, as well as thermal damage up to 450 degrees. The hero ingredient that goes hard at work for protection and moisture is our sesame protein ingredient!

A: Hi there, Great question! Yes, you can add up to three #HairGoal Booster Shots to your leave-in!

A: Hi there! Gosh, that's a lot of hair goal love :). We recommend keeping it to 3 #hairgoal booster shots. It is not currently possible to put more than 3 #hairgoals in each bottle and still be able to mix evenly. We're confident you'll find that 3 hair goal booster shots can cover your...well, hair goals! We hope you love it Function of Beauty #beautynerds team

A: Hi there! We're so glad our #hairgoal booster shots caught your eye :) Function of Beauty #hairgoal booster shots are designed to work best with Function of Beauty shampoo and conditioner, also found exclusively at Target and Target.com. You can pick a base for your natural hair type, and add up to 3 #hairgoal booster shots to customize your hair care. If you want to add the #hairgoal booster shots to other brands of shampoo and conditioner, we believe it is safe to do so but unfortunately can't guarantee you'll achieve your hair goals with that combination of ingredients. We hope you'll give our Function of Beauty shampoos and conditioners a try!
