HG
daily scalp serum for less shedding
Lock it in with HG Lock Drops — your once-a-day, anti-shedding scalp serum.
This fast-absorbing, non-greasy formula helps reduce shedding and keep the hair you have for longer. Powered by Epidermal Growth Factors and the HG3 complex—3% Procapil®, 3% Redensyl®, and a Bio-tanical Blend of Rosemary, Aloe, and Mint—it anchors strands at the root, hydrates the scalp, and supports visibly fuller, thicker-looking hair over time.
Boost your results: Pair Lock Drops with the full HG system
Fill the dropper to the 0.5 mL line and apply directly to the scalp. Repeat once more (total of 1 mL per day). Use once daily on damp or dry hair. Tilt head back and distribute evenly, then gently massage into the scalp. Do not rinse.
One bottle provides up to a 30-day supply when used as directed. Individual usage may vary.
A light, clean refreshing scent derived from natural plant extracts - subtle and fresh, not overpowering.

— Marlene M. (5/5)
"I started using the drops and shampoo/conditioner the same day I recieved it in the mail. My shedding increased a bit and my hair is thinner and oily, way more than before. I'm still giving it a try since it has only been a month. I have little new hair growth."
— Kristen H. (3/5)
"Hi, unfortunately your products are highly fragranced and I cannot use them…so waste of money i thought they were all natural but not only do they smell of artificial they also have a thousand ingredients. . so not what I was looking for . I am highly sensitive to anything artificial and so cannot use these lock drop s and the other potions i brought to stop hair loss and will have to chuck them out. . such a waste. . are using the shampoo which is ok but does make my fine hair quite limp so will not be buying more will try another brand."
— Linda T. (1/5)
"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)
"Smells good, feels good but after using everyday for a month, seems to have made no difference."
— Joanne W. (3/5)
"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)
"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)
"Although these products made me seem like I had a very clean scalp and hair, it made my thinning look worse. I thought I had started to see a difference, like it was thinning but I tried to push through. It wasnt until my husband asked me if I started to use something new in my hair. I excitedly said yes, thinking maybe it was because my hair looked better. But it was the opposite. He thought my hair looked thinner. After stopping use, and switching to a new product, my hair seems to already look fuller after stopping these products. They may work for some people, but for me they did not."
— REGAN (3/5)
"I have been using the lock drops for about 6 weeks and have noticed that my hair feels thicker. it seems to change the fullness of my hair. since I have very fine hair, this is a plus for me."
— Sandra E. (5/5)
