Straight Hair Gentle Shampoo & Conditioner with Volumize #HairGoal Booster
I love the Function of Beauty length hair boost! I have long, naturally straight hair. These products make my hair feel so healthy and moisturized, and after years of color damage, I was afraid it would take me long to re-grow my hair to a healthier state. Not only did this aid in growing my hair longer, but it grew strong and after using for several weeks, I had less hair falling out.

[This review was collected as part of a promotion.] Gifted by. I haven't been using this product for long, and I'm not 100% sure what this is supposed to do exactly (I'll update my review after a couple months), but in combination with the Shamp/Conditioner. (I'm about to start using the scalp therapy), my hair feels great. It really does make my hair feel a lot thicker, especially at the root.

If Im being honest I dont know how to judge if this is working or not. I think my hair has felt overall healthy using these products. This was super easy to use I just added it to my shampoo and conditioner. I do think its cool I could pick which boost I would want.

The Straight Hair Custom Lengthening booster is such a unique and effective product! Firstly, the scent is divine- it leaves me wanting to smell my hair all the time and I've received so many compliments. It's so easy to pop open and add to your bottles and I love how compact it is!

Straight Hair Gentle Shampoo & Conditioner with #HairGoal Booster
[This review was collected as part of a promotion.] Having straight hair doesnt always mean it is in great condition. My hair always has different problems and regular shampoos dont quite cut it. Having to get almost 3 different types of shampoos is exhausting and expensive, thankfully Function of Beauty has an amazing solution where you can add up to three boosters in your shampoo to help with each of your problems. I love this idea as I need volume, length and hydration. The smell is amazing and it leaves my hair looking fabulous! Gifted by Function of Beauty x Target.

This is my first time trying a hair booster product, so I wasn't sure what to expect but WOW! I don't think I can live without this now. I absolutely love how my hair feels afterwards and the amount of shine. I can't say for certain if it will lengthen my hair, however I'm going to keep using these and looking forward to the long-term results!

The conditioner works like magic! My hair is typically SO tough and dry even after conditioner use, however this conditioner gets inside each strand and really smooths it out giving me length! I just love the customization in Function of Beauty products.

Coily Hair Gentle Shampoo & Conditioner with #HairGoal Booster
[This review was collected as part of a promotion.] This lengthen booster shot was gifted to me by Function of Beauty x Target. For kinky coily 4c hair, length is one of the struggles we face. This lengthen booster shot specifically takes care of that. I mixed mine with the moisturizer and I am excited to see the results over time.

[This review was collected as part of a promotion.] I love how easy and convenient these little booster shots are to use and put right into the hair products. I used the volume in my shampoo and I added the Lengthening into the conditioner. This is the first time trying this line and I love it. These products make my hair look soft, shiny and healthier.
