Originally posted on Philip Kingsley

Amazing product which rescued my bleached, coloured, dry and damaged hair. I left the Elasticizer for 5 hours on the first use though after reading reviews I didn’t expect this much improvement after one use. Now I’m using once a week and I’m so happy that I can hand comb my hair which was extremely dry and tangled hair a week ago!

Easy to apply and thick enough to stay on as a masque - and helps with knots and making my hair feel strong.

Originally posted on Philip Kingsley

I don’t normally leave reviews but this product definitely deserves one! I have tried so many different conditioners on my fine hair and have never found anything that works - until now. From the first use my hair is less frizzy, soft and not weighed down at all. Highly recommend.

Old Favourite!

Originally posted on Philip Kingsley

I used this over 30 years ago to 'save' my hair from breaking after having highlights and a perm and it was excellent. Now in my 50's I've repurchased. and still the same great results. My hair being very dry feels replenished and looks in much better condition. Thank you PK! xoxo

Really pleased with this conditioner.

Originally posted on Philip Kingsley

Really pleased with this conditioner. My fair is fragile, thinning and very fine. I've used this four of five times now but, right from the start, my hair has looked and felt so much more luxurious. You must leave it on for at least 20 minutes. I also use the Maximiser before blow-drying. Excellent!

⭐⭐⭐⭐⭐ Absolutely love this product!

Originally posted on Philip Kingsley

⭐⭐⭐⭐⭐ Absolutely love this product! My hair feels noticeably softer, smoother and much more manageable after using it. I have naturally wavy hair that can get quite frizzy, and this leaves it feeling beautifully conditioned without weighing it down. It also gives my hair a lovely healthy shine and makes it so much easier to style. Definitely one I’ll keep repurchasing!

Originally posted on Philip Kingsley

I have no idea why I changed my products to something else in the past, as my scalp and hair have suffered! Now I’m back using the itchy flaky regime, plus the Density preserving scalp drops, my menopause scalp and hair shedding have improved. No itchy psoriasis since first couple of washes and conditions, the toner really helped in the first few days, - daily use of the scalp drops and overnight scalp barrier treatments have helped heal raw scalp and hair shedding tremendously. Using the elasticizer strengthened and moisturised my dry hair. I’m never not using Philip Kingsley hair and scalp treatments again!

Brilliant on dry 4c tight coils

Originally posted on Philip Kingsley

I have very tight fine strands of coily ( type 4) hair. This is always great to help infused my hair with moisture and elasticity. I am able to mitigate damage from detangling significantly. The comb/brush even slides so smoothly. Tip, if you find it too think, just spray more water.
