Philip Kingsley's Elasticizer has long been hailed as a miracle worker for dry, frizzy, and curly hair. This pre-shampoo treatment promises to restore elasticity, add shine, and tame unruly locks. But does it live up to the hype? We put it to the test.
What is Philip Kingsley Elasticizer?
Elasticizer is a deeply conditioning pre-shampoo treatment developed by trichologist Philip Kingsley. It's formulated with botanical oils, including castor oil, olive oil, and almond oil, to nourish and hydrate the hair. The product is designed to be applied to damp hair before shampooing, left on for 10-20 minutes, then rinsed out.
The treatment is particularly recommended for those with dry, damaged, or color-treated hair, as well as those with naturally curly or frizzy textures. It aims to improve hair's elasticity, reduce breakage, and enhance manageability.
Our Experience
We tested Elasticizer on a mix of wavy and curly hair types that were prone to frizz and dryness. After just one use, the results were noticeable. Hair felt softer, looked shinier, and had a noticeable reduction in frizz. The treatment didn't weigh hair down, which is often a concern with heavy conditioning masks.
According to Philip Kingsley's website, clinical testing showed that 85% of users reported a significant improvement in hair's condition after using Elasticizer. This aligns with our own observations, as the product delivered on its promises of smoother, more manageable hair.
How to Use Elasticizer for Best Results
For optimal results, apply Elasticizer to towel-dried hair, focusing on the mid-lengths and ends. Comb through to ensure even distribution, then cover with a shower cap or warm towel to help the product penetrate. Leave on for at least 10 minutes, or longer if hair is particularly dry. Rinse thoroughly, then shampoo and condition as usual.
For those with extremely dry or curly hair, leaving the treatment on overnight (covered with a shower cap) can provide an intensive moisture boost. However, this is not recommended for those with fine hair, as it may lead to over-conditioning.
Why It Works
The key to Elasticizer's success lies in its blend of oils. Castor oil is rich in ricinoleic acid, which helps smooth the hair cuticle and lock in moisture. Olive oil penetrates the hair shaft to strengthen and repair, while almond oil adds softness and shine. Together, these ingredients work to restore the hair's natural lipid barrier, preventing moisture loss and reducing frizz.
Unlike many silicone-based frizz-fighting products, Elasticizer works from within, addressing the root cause of dryness rather than just coating the hair. This makes it a more sustainable solution for long-term hair health.
Who Should Use It?
Elasticizer is suitable for all hair types, but it's especially beneficial for those with:
- Dry or damaged hair
- Curly or coily textures
- Color-treated or chemically processed hair
- Heat-styled hair
If you have fine hair, start with a small amount and focus on the ends to avoid weighing hair down. The product is also vegan and cruelty-free, making it a great choice for conscious consumers.
Final Verdict
Philip Kingsley Elasticizer is a worthy investment for anyone struggling with frizz and dryness. It delivers visible results from the first use, and with regular use, it can transform the overall health and appearance of your hair. At £34.50 for a 200ml bottle, it's not the cheapest treatment on the market, but a little goes a long way, and the results speak for themselves.
If you're looking for a reliable solution to tame frizz and add shine, this cult classic is definitely worth trying.
