Kerasilk is an affordable haircare brand that may have fallen off your radar and I’m about to put them back on because they’ve just released a new bond building treatment under $50.
At Adore Beauty, we’re so happy to hear so many of you are paying more attention to your damaged strands by adding more healthy hair products to cart.
One of the best products for damaged hair is bond repairing and bond rebuilding treatments which are brilliant at restoring and giving second life to dry, damaged and brittle hair.
So when Kerasilk launched a deep-acting treatment designed for “remarkable repair and resilience” my overgrown, dry-ish summer hair was very interested.
The best part? It’s a leave-in!
So for people like me who detest jumping back in the shower after I’ve dried off and want my hair to soak in the goodness for as long as possible, this was even more of a drawcard.
Ideal for all hair types, I had my colleague Maddy try it on her hair too, and of course it wouldn’t be a hair product road-test if I didn't rope my mum into trying it on her dry, coloured hair so I could really gauge how good this treatment was.
Keep scrolling to find out more on the new Kerasilk Strengthening Bond Builder as well as our mini reviews.

What Is Kerasilk Strengthening Bond Builder.

Whether your tresses look or feel damaged from colouring, metals, heat styling or the daily exposure to environmental aggressors, helping to revive them with something like a bond repair treatment is key.
They do the absolute most to restore frizzy, damaged, lifeless hair and broken hair bonds from the inside out.
Here’s some other features of this new deep-acting treatment from Kerasilk:
  • The Kerasilk Strengthening Bond Builder works to strengthen bonds after each application.
  • Restores even highly damaged and weakened hair from within by up to 98%.
  • Hair is left softer and it’s ideal for all hair types.
  • Is also designed to fortify hair against future damage.
  • Infused with Biomimetic Silk (a vegan and sustainable alternative to traditional animal-derived silk) and bondamide.
  • Goes deep into the hair's cortex, rebuilding and strengthening hair bonds. This process repairs brittle, dull, or rough hair.
  • Is cruelty-free and a 100% vegan formula.
  • Is packaged in 70% PCR (post-consumer recycled) material.

Our Kerasilk Strengthening Bond Builder Reviews:


Any treatment or hair product I don’t have to set a timer on is something I’m instantly drawn to and instantly adding to cart (its affordable price tag is a bonus).
So like I said earlier, this deep-acting treatment had me at ‘leave-in’.
Next, the smell!
If you don’t already know, I’m a big fragrance person (I’m super lucky not to be allergic) and always want my body, skin and hair to smell delicious.
If I could describe the scent, it would be “fancy jellybeans”. Softly sweet.
The fast-absorbing texture was also notable. Its silky consistency feels lovely to work through the hair and hands aren’t left sticky and hair isn't either.
Doesn’t weigh down the hair at all and I loved how quickly my hair drank it up.
After giving it a quick blow dry (but before going over with a straightener), the result was subtle, but definitely noticeable. There was shine and there was lots of softness.
This image was a day after having styled over with my ghd:

The final test was mum. I routinely make her road-test all the 'dry hair' and 'age-management' things because of her brittle, coloured hair and beautifully ageing skin (she’s not complaining).
When she hopped out of the shower and towel-dried her hair I asked her how it feels.
She said her hair was feeling noticeably softer and for one wash that’s a pretty great result.
When I was straightening her hair for her I could feel the softness too, and when I was done, I could see the results. Soft, shiny and fluffy (in a good 'give you body' way).
According to the brand, the Kerasilk bond treatment also promises to: “significantly improve the elasticity of each hair strand (clinically tested in comparison to untreated hair) and provide natural shine and increased smoothness.”
I felt like I saw this promise in real time on my mum’s hair:

Now, time for Maddy's review...

Maddy’s Kerasilk Strengthening Bond Builder Review.

"This Kerasilk bond builder was the perfect addition to my current hair routine - as it not only seriously improved the look and feel of my hair, it was also super easy to use.
First up, the smell is absolutely delicious, and personally that’s a make or break for hair products.
Next I loved that it was a leave-in for towel tried hair.
I let my hair air dry on hair wash days, so I could tell that the glorious shine was from this Kerasilk builder as it was the only thing I put in my hair after double-shampooing and conditioning.
Even better was that I felt the effects days after using the leave-in: that pic above?
That’s my hair after a full day in the office, with only a hot brush run through it in the morning to tackle some of the frizz. Incredible!

Final Verdict.

If you’re at the start of embarking on a healthy hair journey, we’d defnitely start with a hair treatment like this one.
