Damaged hair has no shortage of product claims thrown at it. What makes the epres review worth paying attention to is the founder’s pedigree: Eric Pressly is a material scientist and one of the original co-creators of Olaplex, the brand that put bond repair on the beauty map. When someone with that background launches a new treatment, it’s reasonable to take a closer look at what they’ve built differently.
epres Bond Repair Treatment uses a patented Biodiffusion™ Technology and a four-ingredient, waterless, quat-free formula designed to re-link broken disulfide bonds in hair. The pitch is that it’s simpler and pH-neutral compared to acid-based bond builders, which the brand says allows for faster and more effective repair without disrupting hair’s natural environment.
The pricing reflects that premium positioning. The Starter Kit is $50 for a 4–6 week supply, refills run $34, and the Deluxe Starter Kit is $75 for an 8–12 week supply. That makes epres more of a committed routine investment than a one-off treatment.
What Is epres?
epres is a hair care brand built around patented bond repair science, founded by Eric Pressly – co-inventor of the bond-building category and one of the original developers behind Olaplex. The brand’s core product is the Bond Repair Treatment, a pre-shampoo spray designed to repair disulfide bonds broken by chemical treatments, heat styling, bleaching, and everyday mechanical damage.
What sets epres apart from most bond repair brands is the formula philosophy. The treatment is waterless and quat-free, using just four vegan, biodegradable ingredients. It works in 10 minutes, doesn’t leave hair greasy, and is designed as a one-step solution rather than a multi-product system. The brand also runs a refill program using concentrate vials to reduce plastic waste.
Beyond the original Bond Repair Treatment, epres has expanded into a Healthy Hair System – adding a Healthy Hair Shampoo and Conditioner designed to complement the treatment. Free shipping is available on qualifying orders, and a 15% subscription discount applies to refill orders.
epres Products We Used
We focused on the three products that form the complete epres routine: the Bond Repair Treatment Starter Kit as the core product, the Healthy Hair Shampoo and Conditioner as supporting pieces, and the refill concentrate system to understand the longer-term cost picture.
Bond Repair Treatment Starter Kit – $50
The Bond Repair Treatment is the product epres was built on, and it’s the clearest reason to try the brand. The Starter Kit includes a reusable spray bottle and a 4–6 week supply of Bond Repair Concentrate at $50. After that, refill vials are $34 each. The format is straightforward: spray generously onto dry hair until fully saturated, leave for 10 minutes, then shampoo out.
On damaged, color-treated, or heat-styled hair, the results are genuinely noticeable from early use. Hair feels softer and more manageable after the first application, and the smoothing and frizz-reduction effect builds over repeated treatments. InStyle has listed it among the top bond repair treatments for damaged hair, and real-use accounts consistently point to visible improvement within the first two to three uses.
The one honest limitation is cost over time. At $34 per refill for a 4-6 week supply, regular use adds up. The subscription option reduces this to around $29 per refill with free shipping, which makes the ongoing cost more manageable – but it’s still a meaningful routine investment compared to drugstore alternatives.
Best for: damaged, color-treated, bleached, or heat-styled hair needing structural repair
Potential drawback: ongoing refill cost is real; best suited to shoppers who will use it consistently rather than occasionally

Healthy Hair Shampoo – $70
The Healthy Hair Shampoo is designed to complement the Bond Repair Treatment rather than replace it. The brand describes it as a damage-protective shampoo that leaves hair noticeably cleaner, lighter, and revitalized with healthy shine. It’s part of the full Healthy Hair Bond Repair System alongside the conditioner, and buying all three together at a bundle price reduces the per-product cost.
In practice, the shampoo works best when understood as a maintenance product between Bond Repair Treatment sessions rather than a standalone repair tool. It keeps hair in better condition between treatments and extends the benefit of each application. On its own, it’s a quality shampoo – but the real value is in using it as part of the full system.
For shoppers who want the full epres experience, buying the system makes sense. For those who just want to try the brand, starting with the Starter Kit alone is the better entry point.
Best for: shoppers already using the Bond Repair Treatment who want to maintain results between sessions
Potential drawback: less compelling as a standalone purchase; best as part of the full system

Bond Repair Concentrate Refills – $34 (or $29 with subscription)
The refill system is worth understanding before committing to epres, because it defines the real cost of making this a regular routine. Each refill vial is $34 for a 4–6 week supply, or $29 with a subscription. The format is simple: pour the concentrate into the reusable spray bottle, add water, shake, and it’s ready. The brand frames this as both an environmental choice and a practical one – you keep the spray bottle and only replace the concentrate.
For shoppers who use epres consistently, the subscription model makes the most financial sense. At $29 per refill with free shipping, the per-use cost is reasonable for a treatment that’s producing visible results. For occasional users, the cost-per-use calculus is harder to justify. epres works best as a committed routine, not a once-in-a-while product.
The sustainability angle is genuine – reducing plastic waste through concentrate refills is a meaningful design choice, and it aligns with the brand’s four-ingredient, biodegradable formula philosophy.
Best for: regular users who want to reduce plastic waste and lock in lower per-refill pricing
Potential drawback: the ongoing cost requires consistent use to feel justified

- Reusable spray bottle and refill concentrate system reduces plastic waste.

Who Is epres Best For?
epres is best for people with genuinely damaged hair – color-treated, bleached, heat-styled, or chemically processed – who want a science-backed treatment they can use consistently at home. It’s particularly compelling for shoppers who have tried Olaplex and want to explore what the original co-creator has built with a different formula approach.
It’s less suited to people with healthy, undamaged hair who mainly want a conditioning boost, or to shoppers looking for a low-cost one-time treatment. epres delivers most of its value through repeated use, which means it makes most sense for buyers who are willing to commit to a regular hair care routine.
epres vs Alternatives
Compared with Olaplex, epres uses a simpler formula with fewer ingredients and a pH-neutral approach, while Olaplex offers a broader multi-step product range that is deeply embedded in the salon world. Compared with K18, epres requires a 10-minute rinse-out application versus K18’s leave-in format – a practical difference for shoppers who want minimal routine steps. epres stands out most for buyers who specifically want a waterless, quat-free formula and the refill-based sustainability model.
| Brand | Price Level | Key Differentiator | Best For |
| epres | Premium | Patented bond repair, founded by Olaplex co-creator | Damaged, color-treated, or heat-styled hair |
| Olaplex | Premium | Widest bond repair range, salon standard | Salon clients and at-home treatment seekers |
| K18 | Premium | Leave-in molecular repair, no rinse needed | Shoppers wanting a quick no-rinse treatment |
Final Verdict
epres delivers genuinely strong results for damaged hair, and the science behind it is credible. For shoppers dealing with color damage, heat damage, or breakage, the Bond Repair Treatment is one of the more compelling at-home options available – especially given the founder’s background in the bond repair category.
Start with the Starter Kit at $50 to understand whether the treatment works for your hair before committing to refills. If you see results, the subscription refill model at $29 per cycle makes the long-term cost more manageable. Add the Healthy Hair Shampoo and Conditioner once you’re confident in the base treatment.

How often should you use epres?
The brand’s refill sizing suggests regular use every 4–6 weeks, though it can be used more frequently for heavily damaged hair. Consistent use over multiple sessions delivers noticeably better results than occasional treatment.
Does epres work on all hair types?
Yes – the brand positions epres as suitable for all hair types and textures. It is particularly well-suited to color-treated, bleached, heat-styled, or chemically processed hair where structural bond damage is present.
Is epres worth the ongoing cost?
For people with genuinely damaged hair who use it consistently, the results justify the price for most buyers. The subscription model at $29 per refill with free shipping makes the ongoing cost more manageable. For occasional use or healthy hair, the value proposition is harder to make.
