About the Brand
Brand logo
Founded by celebrity hairstylist Wendy Iles, Iles Formula was created from decades of hands-on experience working with the world’s most demanding hair—on fashion runways, red carpets, and editorial sets. After years of witnessing hair damage caused by over-processing and harsh products, Wendy Iles set out to create a line of high-performance haircare that prioritizes hair integrity, strength, and longevity. The result is a tightly edited collection of luxury formulas that blend advanced cosmetic science with refined simplicity, earning a cult following among professionals and clients alike.

Iles Formula treats hair with the same precision and respect as fine couture, focusing on preserving the cuticle and strengthening the hair fiber at every step. Rather than masking damage, each formula is designed to protect against it—improving elasticity, reducing breakage, and maintaining optimal moisture balance. Highly concentrated yet lightweight, the products deliver multiple benefits in one step, supporting all hair types while remaining especially effective for color-treated, fragile, or chemically processed hair.

At the core of Iles Formula is a philosophy of intelligent formulation: gentle cleansing systems, silk proteins, targeted conditioning polymers, and nourishing botanical ingredients work in harmony to smooth, strengthen, and protect without build-up. Each product is carefully calibrated to respect the hair’s natural structure while enhancing shine, softness, and resilience. This disciplined, results-driven approach—paired with an elegant sensory experience—defines Iles Formula’s reputation for effortless luxury and visibly healthier hair.

Stimulates Hair Growth

Revitalise your scalp and promote healthy, strong hair growth. By stimulating hair follicles and improving blood circulation, you can encourage new hair growth while strengthening existing strands. This leads to thicker, fuller hair with enhanced texture.

Anti-Hair Loss

Anti-Hair Loss treatments work by optimising your hair growth cycles to reduce excess hair loss and stimulate new hair growth. While hair loss is natural, factors like hormonal changes, stress, hair damage, genetics, and nutritional deficiencies can make it worse. These factors disrupt hair growth cycles, cause inflammation, weaken hair structure, and reduce hair anchoring, leading to more hair loss and slower regrowth.

To combat this, anti-hair loss products target multiple aspects of hair health. They inhibit hormones like dihydrotestosterone (DHT) that contribute to hair loss, enhance hair anchoring to the scalp, and stimulate collagen production to strengthen hair structure. Additionally, they reduce inflammation to protect hair follicles, normalise hair growth cycles, and shield your scalp from environmental damage and irritation. This comprehensive approach helps you maintain healthier, stronger hair and promotes new growth.

Repairing

Damaged hair is typically identifiable by a rough, straw-like texture, increased difficulty in styling, and visible signs such as broken strands and split ends. These symptoms reflect underlying structural compromise within the hair fiber, often resulting from external aggressors such as chemical treatments, thermal styling, UV exposure, and mechanical stress.

Lipid Cement Deficiency occurs when the cuticle is exposed to aggressive treatments or environmental factors, and stripped of essential lipids, resulting in increased permeability. This loss compromises its barrier function, leaving the underlying cortex vulnerable to protein and lipid degradation.

Split Ends occur when the lipid distribution is uneven along the length of the hair shaft, with the ends being the most affected. The hair ends, being older and more frequently exposed to damaging elements, contain up to 30% less ceramide than the root, making the hair more prone to splitting and breakage.

Cuticle Scale Separation occurs when the lipid cement causes the scales to lift and disconnect, exposing the cortex and increasing transepidermal water loss (TEWL). This results in excessive dehydration, leaving the hair dry, brittle, and more susceptible to further damage.

Keratin Fiber Degradation occurs when the lipid and protein components weaken the keratin matrix, the hair loses tensile strength, flexibility, and resilience.

Loss of Shine occurs when the hair is damaged and exhibits irregularities and surface roughness due to disrupted scales and lipid loss. These irregular surfaces scatter light unevenly, leading to a dull, lackluster appearance.

Follicle Repair

Hair follicle repair restores optimal growth and density by reactivating dormant follicles and balancing the hair growth cycle. Ageing, stress, and hormonal imbalances can shorten the anagen (growth) phase and prolong the telogen (resting) phase, leading to thinning. Repairing follicles involves stimulating dermal papilla cells, enhancing blood circulation, and supporting keratin synthesis to strengthen the hair’s structure. By reducing inflammation and oxidative stress, follicles regain their ability to produce thicker, stronger, and healthier hair over time.

Hydrating

Hydrating your hair means boosting its water content to ensure strands stay resilient, flexible, and healthy. Proper hydration is key to preserving the integrity of your hair's cuticle. When well-hydrated, the cuticle lies flat and smooth, creating a barrier against environmental damage and reducing friction between strands, which results in less tangling and a smoother texture. Heat styling, sun exposure, and harsh chemical treatments can strip your hair of its natural moisture. Using gentle haircare products designed to hydrate without weighing your hair down helps prevent dryness, brittleness, and breakage while enhancing shine and making your hair more manageable.

Colour-Protecting

Colour Protection in haircare is essential for maintaining vibrancy, strength, and long-term hair health, especially after colouring or chemical treatments. Daily exposure to UV rays, frequent washing, and thermal styling can break down pigments, weaken the cuticle, and leave hair dull and fragile.

This is where targeted colour-protecting care becomes critical. By shielding the hair from oxidative stress and helping the cuticle scales remain closed, it helps lock in colour and preserve luminosity. Hair stays radiant and reflective, while structural damage caused by treatments like bleaching is reduced. With consistent use, coloured hair looks brighter for longer, feels stronger, and is better protected against future fading and external aggressors.

Nourishing

Effective hair nourishment involves the restoration of the scalp’s barrier function, which plays a critical role in maintaining hydration and overall hair health. By enhancing barrier integrity, moisture is better retained and bioactive compounds are able to penetrate the hair cuticle, delivering deep nourishment to the cortex. This process contributes to structural reinforcement, improved elasticity, and greater resilience of the hair fibre.

Strengthening

Strengthening in haircare is all about restoring your hair's healthy structure and enhancing its resilience against damage, breakage, and the stresses of daily styling, such as heat exposure. Strengthening haircare products deliver essential components like proteins, hydration, and lipids that work together to reinforce hair strands. They support internal hair bonds, restore moisture, and coat the outer layer to protect and smooth, resulting in a shinier, smoother finish. By promoting a healthier hair structure, these products encourage faster hair growth and improve manageability.

Biotinoyl Tripeptide-1

Biotinoyl Tripeptide-1 is a powerful, botanically derived, breakthrough active that promotes hair growth naturally by targeting the hair at the root. It works by stimulating key components of the hair follicle, helping to ignite growth in the root area, strengthen hair follicles, and improve anchoring of the hair fiber within the scalp. By reinforcing follicle structure and supporting healthy growth cycles, Biotinoyl Tripeptide-1 helps reduce hair loss and hair breakage, leading to stronger, fuller-looking hair over time.

Apigenin & Oleanolic Acid

A synergistic botanical complex known to help counteract hair thinning. Apigenin improves microcirculation around the follicle, supporting nutrient delivery, while oleanolic acid helps inhibit excess DHT activity, which is linked to androgen-related hair loss.

Niacinamide

Improves scalp barrier function, boosts circulation, and supports healthy follicle metabolism while helping regulate oil and reduce redness or irritation.

Green Tea Leaf Extract

Provides antioxidant protection and helps reduce oxidative stress around the hair follicle, supporting healthier hair growth conditions.

Apple, Tomato & Wasabi Extract

Apple, Tomato & Wasabi Extracts work synergistically to support follicle vitality and protect the scalp from premature ageing. Wasabi extract helps stimulate dermal papilla cell activity, which plays a key role in healthy hair follicle development and stronger hair growth at the root. Tomato and apple extracts, rich in antioxidants and phytonutrients, aid cellular rejuvenation while helping reduce oxidative stress that contributes to scalp ageing and weakened hair. Together, these botanical extracts help create a healthier scalp environment that supports resilient follicles, improved hair quality and long-term vitality.

Spotlight

Hair Loss

Anti-hair loss treatments are designed to refine and optimize the hair growth cycle, minimizing excessive shedding while promoting the emergence of new, healthy hair. While some hair loss is a natural part of life, factors such as hormonal imbalances, stress, genetics, nutritional deficiencies, and external damage can disrupt this balance, leading to weakened strands, inflammation, and diminished regrowth. Luxury anti-hair loss solutions take a holistic and scientifically advanced approach, addressing multiple dimensions of hair health. By neutralizing the effects of dihydrotestosterone (DHT), a key contributor to hair thinning, these treatments fortify the hair’s anchoring system and stimulate collagen synthesis to strengthen the hair structure from root to tip. They also calm inflammation, protecting the delicate hair follicles, while harmonizing the natural hair growth cycle. Enriched with protective and restorative ingredients, these formulations shield the scalp from environmental stressors, creating the ultimate foundation for vibrant, resilient hair. The result is a transformative experience—luxuriously healthier, stronger hair with visibly renewed density and vitality.
