From broken bonds to brittle nails, we're separating the beauty myths from the science.
There's no shortage of advice when it comes to looking after your hair and nails. One minute you're being told to avoid heat altogether, the next you're being promised that a strengthening treatment can fix years of damage overnight.
And then there's bond building. It's become a familiar term in haircare, but what does it actually mean? Can bond repair help with nail damage, too? And are all strengthening treatments doing the same thing?
We thought it was time to separate fact from fiction. Here's what you really need to know about hair and nail repair, and why the science behind your products matters.
HAIR MYTHS
Myth 1: Bond-building treatments are only for bleached or coloured hair.
The truth: Chemical processing isn't the only thing that can damage your hair.
Colouring and bleaching can certainly take their toll, but everyday habits play a part, too. Heat styling, brushing, environmental exposure and general wear can all contribute to damage over time.
That's why bond repair isn't just something to think about after a salon appointment. It's about supporting the structure of your hair, whatever your routine looks like.
The epres™ Bond Repair Treatment was developed to target broken disulfide bonds associated with chemical, mechanical and environmental damage. Its patented Biodiffusion™ Technology continues working even after the hair has dried, making it a treatment designed to fit into everyday haircare routines.
Myth 2: All bond builders work in exactly the same way.
The truth: The term "bond builder" doesn't tell you everything about a product.
Different formulations use different technologies, ingredients and application methods. Some treatments involve multiple steps, while others are designed to work in a single application.
epres™ takes a one-step approach. Its Bond Repair Treatment is designed to actively repair broken disulfide bonds without disturbing the hair's natural pH. The spray-on formula is left on for at least 10 minutes before washing and styling as usual.
It's a good reminder that when it comes to bond repair, the science behind the formula matters just as much as the claims on the bottle.
Myth 3: If my hair feels soft, it must be repaired.
The truth: Softness and structural repair aren't necessarily the same thing.
Conditioning ingredients can make hair feel smoother, easier to manage and less prone to tangling. But that doesn't automatically mean underlying structural damage has been addressed.
This is where understanding the difference between your products becomes useful.
The epres™ Bond Repair Treatment is designed to target damaged bonds within the hair structure, while the Healthy Hair Shampoo and Conditioner are part of the wider routine for keeping hair clean, conditioned and manageable. They're designed to work alongside the treatment rather than replace its specific purpose.
Think of it as giving your hair different kinds of care, rather than expecting one product to do absolutely everything.
Myth 4: More products mean better results.
The truth: A longer routine doesn't automatically mean a better one.
It's easy to assume that repairing damaged hair requires a complicated combination of masks, oils, treatments and leave-ins. But sometimes, a straightforward routine with products that serve distinct purposes makes more sense.
The epres™ Bond Repair Treatment is designed as a single-step treatment, recommended once or twice a week. For everyday care, the Healthy Hair Shampoo and Conditioner provide the foundation of a simple haircare routine.
For anyone who prefers to keep things simple, the Healthy Hair 3-Step System brings the treatment, shampoo and conditioner together.
And when your treatment runs low, the concentrate refill packs allow you to reuse your original spray bottle rather than replacing the entire kit.
Myth 5: Once hair is damaged, there's nothing you can do.
The truth: Hair can't biologically regenerate, but that doesn't mean you're out of options.
Hair is made from non-living keratin fibres, so repairing damage isn't quite the same as healing skin. However, targeted treatments can improve certain properties of damaged hair, including strength and resistance to breakage.
That's the principle behind epres™ Bond Repair Treatment. Developed by materials scientist Dr Eric Pressly, its patented technology targets broken disulfide bonds to help restore hair strength and improve its overall condition.
It's not about promising to turn back time. It's about giving damaged hair the care and support it needs.
NAIL MYTHS
Myth 6: Bond building is just for hair.
The truth: The science of bond repair isn't limited to your strands.
Just like hair, nails have a complex structure. When nails become brittle, weak, peeling or prone to splitting, simply adding another layer of polish isn't necessarily addressing the underlying issue.
Enter ePhD.
Developed by epres™ founder Dr Eric Pressly, ePhD Bond Repair Nail Treatment uses patented Biodiffusion™ Technology to penetrate the nail and target damaged bonds within its structure. It uses the same bonding molecule found in epres™ hair treatments, adapted for nail repair.
It's the same scientific thinking, applied to a different part of your beauty routine.
Myth 7: Nail strengtheners work by coating the nail.
The truth: Not all nail treatments are designed to sit on the surface.
Traditional strengthening products may focus on creating a coating or protective layer. ePhD takes a different approach, using a formula designed to penetrate the nail and support repair from within.
Its formula contains just two ingredients and is 100% vegan, biodegradable and polymer-free.
The treatment can be used on clean, bare nails or underneath polish and gel manicures, making it easy to incorporate into an existing nail routine.
So whether you prefer a natural manicure or never go without your favourite polish, nail care doesn't have to mean changing your entire routine.
Myth 8: Hair and nail repair require completely different science.
The truth: The applications are different, but the underlying innovation can be shared.
This is where the connection between epres™ and ePhD becomes particularly interesting.
Both were developed by Dr Eric Pressly, whose background is in materials science and patented bond-repair technology. epres™ applies this innovation to damaged hair, while ePhD brings the same bonding molecule and Biodiffusion™ approach to nail repair.
The products aren't interchangeable: hair and nails have different structures and require formulations suited to each. But the shared approach is to look beyond surface-level conditioning and target damage within the structure itself.
Hair and nail care doesn't need to be complicated, but understanding what your products actually do can make all the difference.
Because when it comes to hair and nails, it's worth looking beyond the surface. Good care starts with understanding what's happening underneath.
