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)

Q&A

Im confused. Does this replace the AM/PM set that you sell? Is this better?
Hi Joe, Thanks for your question! We actually recommend using either the Power Couple or the Lock Drops as your go-to solution – not both together. That’s because they’re both designed to deliver similar benefits (like reducing excess hair fall, strengthening follicles), but in slightly different ways. Our team would love to help you decide which option is best for you and your routine. Please reach out anytime, and we'd be happy to help!
I already use the procapil spray every wash day. This also has procapil. Is it safe to use this alongside the procapil and/or intensive sprays? If so, how would you recommend incorporating the hair lock serum with the spray tonics? Thank you.

Can you use this in combination with HG Intensive and Procapil pproducts or does this replace the two?
