Reviews

Slight improvement

"I used this in conjunction with supplements and bondi boost shampoo and conditioner after a large amount of hair fall whilst losing weight. I used this for a couple of months and I do have a small amount of baby hairs sprouting, but not enough that I would believe it worth repurchasing."

— Steph (4/5)

I apply this every night

"I apply this every night before bed. These drops literally changed my hair growth in such a positive way. The drops saved my hair and I see less fallout and my hair is also growing. I am so grateful for these drops and I will continue to buy more."

— Iliana M. (5/5)

Finally Seeing Real Progress and It Actually Feels Good

"Real Progress & Healthy Hair I’ve been using the BondiBoost HG Lock Drops alongside the entire HG hair system for well over a couple now and I’m really happy with them. I’ve started noticing real progress with my hair looking fuller and healthier. The drops feel lightweight and easy to use, and the slight tingle makes it feel like the product is actually working. A little bit of hair care magic in a bottle! Definitely worth trying if you want healthier-looking hair and are willing to stay consistent."

— Bre B. (5/5)

Lightweight & So Easy to Use

"I've only used the Lock Drops Anti-Shedding Scalp & Hair Serum once so far, but I already have a great first impression. One of the things I was most worried about was it making my scalp feel greasy, but it didn't at all. The formula feels lightweight, absorbs quickly, and leaves my hair looking fresh instead of oily. I also love that it's designed with ingredients to help reduce shedding and support healthier-looking hair. It's easy to incorporate into my routine, and I'm excited to continue using it consistently to see the long-term results."

— Amanda C. (5/5)
