Philip Kingsley Elasticizer Deep-Conditioning Treatment

About Philip Kingsley Elasticizer

Philip Kingsley is one of the world's most respected names in hair science. The Elasticizer was originally created for Audrey Hepburn — a bespoke treatment to restore her hair after years of styling and processing. It has since become one of the most iconic hair treatments ever made, and for good reason: it works.

Used before shampooing, the Elasticizer penetrates deep into the hair cuticle to deliver intense moisture, restoring the hair's natural elasticity and flexibility. The result is hair that feels silkier, stronger and more manageable — with visible results from the very first application that build with continued use. The formula also provides UV protection even after rinsing, helping to prolong the life of colour treatments.

How to Use

Before shampooing, thoroughly wet hair and apply the Elasticizer in sections. Work into hair with fingertips. Cover with a shower cap and leave for at least 20 minutes — preferably 60 minutes or more for maximum benefit. Rinse well, then follow with your Philip Kingsley shampoo and conditioner. Finer hair textures should double-shampoo to ensure all product is removed. For best results, use at least once a week.

• ✧ Overnight treatment: apply, cover with a shower cap and leave on overnight for an enhanced result
• ✧ Pre-gym: apply before your workout and shampoo out post-gym
• ✧ Styling cream: use on natural tightly coiled hair as a styling cream

Who It's For

• ✧ Damaged or over-processed hair — the Elasticizer was designed for exactly this
• ✧ Colour-treated hair — UV protection helps preserve colour vibrancy between salon visits
• ✧ Dry, brittle or fragile hair — restores flexibility and reduces breakage
• ✧ All hair types — including fine hair (double-shampoo to remove fully)
• ✧ Natural and coily hair — can be used as a styling cream on tightly coiled textures

Which Size?

• ✧ 75ml — ideal for trying the Elasticizer for the first time, or for travel
• ✧ 150ml — the better value option for regular weekly use

Frequently Asked Questions

Is the Elasticizer a conditioner or a mask?
Neither — it's a pre-shampoo treatment, which means it's applied before you shampoo rather than after. This allows it to penetrate the hair cuticle more deeply than a standard conditioner.

How long should I leave it on?
At least 20 minutes, but the longer the better. Philip Kingsley recommends 60 minutes or more for maximum benefit, and it can be left on overnight under a shower cap.

Is it suitable for fine hair?
Yes — but fine hair should double-shampoo after use to ensure all product is fully removed and hair doesn't feel weighed down.

Will it help with colour-treated hair?
Yes — the formula provides UV protection even after rinsing, which helps prolong the life of colour treatments and reduce fading.

Do you offer free UK delivery?
Yes — free standard UK delivery on all orders over £50.

I have a question — can I get help?
Of course. Oh So Luxe is a small, owner-run UK boutique and you'll always hear back from a real person, quickly.
