The Benefits

  • - + Stimulates Hair Growth
  • - + Hair Strengthening
  • - + Hair Follicle Repair
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.

  • - + Hair Follicle Repair
Hair 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.

  • - + Stimulates Hair Growth
  • - + Hair Strengthening
  • - + Hair Follicle Repair
Hair 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.

Active Ingredients

  • - + Biomimetic Peptide & Red Clover Extract
  • - + Rep’Hair (Vegetable Protein)
  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Abyssinian Oil (Eyelashes & Brows)
Biomimetic Peptide & Red Clover Extract

Biomimetic Peptide & Red Clover Extract help minimise hair loss by stabilising hormonal fluctuations, specifically in Dihydrotestosterone (DHT) levels, which are linked to hair loss. They also reduce scalp irritation and enhance cell renewal processes to normalise hair growth cycles, thereby reducing excessive hair loss and stimulating new hair growth.

  • - + Biomimetic Peptide & Red Clover Extract
  • - + Rep’Hair (Vegetable Protein)
  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Abyssinian Oil (Eyelashes & Brows)
Rep’Hair (Vegetable Protein)

Rep’Hair (Vegetable Protein) penetrates deeply into weakened hair fibers, delivering essential nutrients to repair and strengthen lashes and brows. Derived from hydrolysed vegetable protein, it moisturises and fortifies the cuticle, preventing damage and breakage. By enhancing resilience and promoting a smoother texture, it revitalises the appearance of lashes and brows for a naturally healthy, polished look.

  • - + Rep’Hair (Vegetable Protein)
  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Abyssinian Oil (Eyelashes & Brows)
Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)

This advanced complex helps regulate melanin production at the follicle level by inhibiting PMEL-17 gene expression, which is involved in pigment formation. The result is a more even-toned, uniform appearance of the brow and lash line. Additionally, Pea Extract is rich in protein and stimulates dermal papilla cells, supporting hair regrowth and reducing shedding, ideal for promoting fuller lashes and brows.

  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Abyssinian Oil (Eyelashes & Brows)
Resveratrol (Eyelashes & Brows)

Resveratrol is a potent antioxidant naturally found in red grapes. When used on eyelashes and eyebrows, it helps neutralise free radicals caused by UV and environmental stressors, protecting the delicate hair follicles from oxidative damage. This protective action helps preserve follicle integrity, reduces inflammation at the root, and supports stronger, more resilient hair. Over time, it contributes to visibly denser, shinier lashes and brows by improving the health of the growth environment.

  • - + Rep’Hair (Vegetable Protein)
  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Abyssinian Oil (Eyelashes & Brows)
Abyssinian Oil (Eyelashes & Brows)

Abyssinian Oil is rich in omega fatty acids, including erucic, oleic, and linoleic acids, which deeply nourish and protect eyebrow and eyelash hairs. It reinforces the cuticle layer, enhances moisture retention, and forms a lightweight barrier that defends against environmental aggressors and mechanical damage from makeup or styling. Known for its rapid absorption and non-greasy finish, it leaves hairs feeling soft and supple while reducing breakage. Its anti-inflammatory profile also helps soothe follicular irritation, encouraging healthier growth cycles and supporting hair density and shine.

Spotlight

Rep’Hair (Vegetable Protein)

Rep’Hair™ (Vegetable Protein) penetrates deeply into weakened hair fibres, delivering essential nutrients to repair and strengthen from within. Derived from hydrolysed vegetable protein, this biomimetic active is rich in amino acids that resemble the natural keratin structure of the hair, allowing for effective absorption and targeted action at the core of the fibre.

Once inside the cortex, Rep’Hair™ works to rebuild internal cohesion, reinforcing protein bonds compromised by chemical treatments, heat styling, or environmental stress. At the same time, it acts on the hair’s surface, moisturising and fortifying the cuticle—the outermost layer of the hair shaft—creating a flexible yet protective film that seals in hydration and reduces surface porosity.

The result is stronger, more resilient hair with visibly improved texture and shine. Split ends and breakage are reduced, elasticity is restored, and the hair feels smoother, softer, and easier to manage. Over time, hair regains its vitality, appearing naturally healthy, polished, and full of life.

Why I love it

  • The efficacy of Biologique Recherche relies not only on its science-driven approach to balancing and curing the skin, but on its prescriptive and tailored nature.
