How Does Nº 77 Leave-In Work?

We tried to find out what makes the Hair La Vie Nº 77 Leave-In conditioner an effective solution for revitalizing hair health. And here is what we discovered:

Nº 77 Leave-In by Hair La Vie is a potent hair care product that harnesses the power of carefully selected ingredients to deliver remarkable results for your hair. This leave-in conditioner contains a nourishing blend of keratin, hydrolyzed silk, horsetail extract, soy protein, and vitamin B5, each playing a vital role in transforming your hair.

Keratin works by repairing and fortifying the hair, reducing breakage, and promoting stronger, healthier locks. Hydrolyzed silk takes charge of smoothing the hair cuticles, resulting in reduced frizz and increased shine. Horsetail extract, enriched with high silica content, enhances hair elasticity and promotes growth. Lastly, soy protein delivers essential amino acids that nourish and strengthen the hair, while vitamin B5 adds moisture and volume.

The combination of these powerful ingredients works synergistically to provide deep hydration, strengthen hair strands, and improve overall hair texture. With Nº 77 Leave-In, you can embrace luscious, healthy-looking hair, as this product improves hair texture, reduces frizz, and enhances shine, leaving your hair looking and feeling healthier than ever.

Nº 77 Leave-In Ingredients – Are They Safe And Effective?

Nº 77 Leave-In by Hair La Vie incorporates a powerful blend of nourishing ingredients that work together to provide exceptional results for your hair. The key ingredients in this premium leave-in conditioner include:


Derived from natural sources, keratin is a protein that plays a vital role in strengthening hair. It helps repair damage, reduce breakage, and promote healthier hair strands. According to a study published in the Biotechnology Reports, keratin has been shown to improve hair strength and resilience.[1].

Dr. Jessica Weiser, a board-certified dermatologist, states, “Keratin is a structural protein that can help strengthen the hair shaft, reduce breakage, and improve hair texture. It acts as a protective barrier, making the hair less susceptible to damage from external factors such as heat styling and chemical treatments.”

Hydrolyzed Silk

Known for its luxurious texture and moisturizing properties, hydrolyzed silk is derived from silk fibers. It works by smoothing hair cuticles, reducing frizz, and enhancing shine. Research published in the Journal of Cosmetic Dermatology highlights the conditioning and protective effects of silk proteins on hair.[2].

As documented in our Beverly Hills MD Lift + Firm Sculpting Cream Review (another product containing this ingredient), hydrolyzed silk also plays key roles in helping the skin look tighter, firmer, and lifted.

Also, Dr. Susan Stuart, a dermatologist, explains, “Hydrolyzed silk is a lightweight protein that can provide moisture to the hair without weighing it down. It forms a smooth coating on the hair cuticles, helping to reduce frizz and enhance shine. It can also protect the hair from damage caused by heat styling tools.”

Horsetail Extract

Extracted from the horsetail plant, horsetail extract is rich in minerals, including silica, which is essential for maintaining hair elasticity and promoting hair growth. According to research published in Nutrients[3], horsetail extracts can be used as hair growth stimulants, hair strengtheners, and hair loss treatments.

According to Dr. Michele Green, a cosmetic dermatologist, “Horsetail extract is rich in minerals, particularly silica, which is essential for strong and healthy hair. It helps improve hair elasticity, making it less prone to breakage. Additionally, it promotes blood circulation to the scalp, which can stimulate hair growth.”

Soy Protein

Derived from soybeans, soy protein is a valuable source of amino acids that nourish and strengthen the hair. It helps improve hair texture and promotes overall hair health. A study published in the Journal of Pharmacopuncture highlights the positive effects of soy protein on hair structure and appearance. It shows that soy protein may promote hair growth and prevent hair loss.[4].

Dr. Zoe Draelos, a renowned dermatologist, states, “Soy protein is a valuable ingredient in hair care products. It contains amino acids that can strengthen the hair strands and improve overall hair texture. Soy protein can also help reduce hair breakage, making the hair appear fuller and healthier.”

Vitamin B5

Also known as panthenol, vitamin B5 is a water-soluble vitamin that provides moisture and volume to the hair, making the hair softer. Our Pantothenic Acid (Vitamin B5) review highlights the benefits and uses of this vitamin including its role in hair health.

Research published in Current Issues in Molecular Biology shows that Dexpanthenol (a precursor of vitamin B5) exacts anti-hair loss effects by increasing hair cell viability, suppressing cell death markers, and elongating the growth phase in hair follicles.[5].

In addition, Dr. Joshua Zeichner, a board-certified dermatologist, explains, “Vitamin B5, is a humectant that attracts and retains moisture in the hair. It acts as a conditioner, leaving the hair hydrated, soft, and more manageable. Additionally, vitamin B5 can add volume to the hair, giving it a fuller appearance.”

Verdict: Based on the benefits of each ingredient, supported by reputable sources, we find the ingredient blend in Nº 77 Leave-In to be highly effective in promoting healthier and more beautiful hair.

    Satisfied..! LOVE IT
    I have long hair and I ordered the shampoo and conditioner. OMG!, as soon as i put it on my scalp i felt the difference, the conditioner was so smooth and silky I had to check to see if my hair were falling as i rinsed it out. No tangles what so ever. I'll never go back to other shampoos and conditioners.
