Excellent product

Originally posted on Philip Kingsley

Love this product as it definitely does what it says without leaving your hair oily or sticky I have fine hair and it’s growing now (lost it all 2 years ago) so it doesn’t tolerate heavy products the PK range has everything I need to preserve and nurture my growing hair excellent product and a very small amount on the ends is perfect

I’ve been using this alongside the density range & my hair condition has been much better. The ends were previously really frazzled looking & this has improved greatly & become smoother whilst also using the bond builder restorative oil

Product smells nice and I

Originally posted on Philip Kingsley

Product smells nice and I think it's doing something to help with the split ends but my hair is so coarse and curly that I need a lot of product. Would be nice if there was an option to buy in different sizes.

Amazing product, it literally eradicates

Originally posted on Philip Kingsley

Amazing product, it literally eradicates split ends! Save countless trips to the hairdressers and you get a ton of compliments about how healthy your hair looks. This product is a game changer for me, I have long, thick hair and without it I’d have to constantly get it cut. Thank you Philip Kingsley!

Originally posted on Philip Kingsley

Alongside elasticizer extreme, bond builder is fantastic. I have long, curly hair and now I have ‘gone grey’, it needs even more protection from dryness and split ends. Bond builder does just the that!

Originally posted on Philip Kingsley

I’d been using another regular bond repair treatment for a while and not really seeing any results, but as soon as I switched over to this I noticed a difference! My hair is softer and shinier, breaking a lot less, and it was very damaged before from bleach and box dye. Absolutely recommend - I’ve been using it as a post-shampoo treatment rather than pre-shampoo (à la Abbey Yung) and it works perfectly, never weighs my hair down and doesn’t leave a residue.

Body Builder worth the investment a little goes a long way to get your bounce and swish back

Originally posted on Philip Kingsley

Following the trend to let my blonde highlighted hair go grey naturally I was looking for a new hair care package to tackle my limp fine lacklustre hair. Initially I bought the Phillip Kingsley Body Building shampoo and conditioner while noticing a big improvement I was gifted a trial size of Bond Builder which made a vast difference and now have bouncy healthy smooth hair that gave me back a confidence that my two years growing out to go natural was worth the long process and have found my winning formula. Thank you for the free trial gift my gamechanger.
