The BondiBoost Best Sellers: Your 3-Step Routine for Thicker, Healthier-Looking Hair
Some products earn best-seller status by accident. These three earned it by actually working. If you're new to BondiBoost — or just wondering what to add to cart next — here's the trio our customers keep coming back for, and exactly how they work together.

1. HG Anti-Thinning Shampoo & Conditioner
The foundation of the routine. This sulphate-free duo cleanses and conditions while targeting the signs of thinning and shedding at the source. Powered by Rosemary to stimulate the scalp, plus plant-based Redensyl® and Procapil®, it works to anchor hair at the root for fuller, healthier-looking strands over time.
Naturally powered, clinically proven:
- 93% saw less shedding in just 1 month*
- 90% saw longer, fuller, thicker hair in just a month*
- 86% less fallout due to breakage after one month of use*
- Safe for chemically and colour-treated hair
How to use: Massage 1–3 pumps into wet hair, lather, and rinse. Follow with the conditioner, focusing on the ends, and rinse thoroughly. Use consistently for the best results — most people notice a difference around the 90-day mark.
Smells like: Zingy natural peppermint for a pep in your step.

2. Lock Drops Anti-Shedding Scalp & Hair Serum
The daily scalp boost. Think of Lock Drops as the step that goes where shampoo and conditioner can't. This lightweight, fast-absorbing, non-greasy serum is powered by Epidermal Growth Factors and the HG3 complex — 3% Procapil®, 3% Redensyl®, and a botanical blend of Rosemary, Aloe, and Mint — to anchor strands at the root and hydrate the scalp.
Customers love how quickly it absorbs (no greasy residue, no weighed-down hair) and how easy it is to slot into a routine, wash day or not.
How to use: Fill the dropper to the 0.5 mL line and apply directly to the scalp. Repeat once more for a total of 1 mL per day. Use once daily on damp or dry hair — tilt your head back, distribute evenly, and gently massage in.
Pro tip: Pair it with the HG Shampoo and Conditioner for faster, longer-lasting results.

3. Miracle Hair Mask
The weekly reset. Where the shampoo and serum focus on thinning and shedding, the Miracle Hair Mask is all about repair and softness. This silicone-free deep conditioning treatment is clinically proven to improve the look of split ends by 84% after just 4 uses, infused with Argan and Jojoba oils for hair that feels hydrated, silky, and frizz-free — without any heaviness.
How to use: Remove excess water from hair, massage a small amount from mid-shaft to ends, and leave in for 15 minutes before rinsing thoroughly. Use once a week in place of conditioner.
Smells like: A fruity pomegranate mojito with notes of apricot and sweet orange.
Why These Three Work So Well Together
Each product is solving a different piece of the puzzle:
- HG Shampoo & Conditioner — daily cleansing that targets thinning at the root
- Lock Drops — a daily scalp treatment for extra shedding support
- Miracle Hair Mask — a weekly deep repair step for softness and shine
Used together, you're covering scalp health, root strength, and strand repair — which is exactly why this combination shows up again and again in our customers' routines (and why it's bundled as the Anti-Thinning Best Seller kit).

The Bottom Line
Great hair days aren't about one miracle product — they're about a routine that actually works with your hair, not against it. Start with the basics, add the serum for extra support, and don't skip the weekly mask. Your hair will thank you.
