[Interview] The best hair tips from the In Haircare team

Since the beginning of the In Haircare adventure, you've stood out for your "in & out" vision of hair care. How can this approach make a difference in keeping hair healthy, strong, and shiny every day?

At In Haircare , we believe that beautiful hair is not only about applying external care, but also about providing essential nutrients from within. The "in & out" approach allows us to act on all components of the hair fiber: strengthening the hair structure, stimulating growth and protecting the lengths against breakage and dehydration. It is this synergy between internal and external care that guarantees stronger, shinier and healthier hair in the long term.

Yet we read everywhere that hair is a dead fiber. Can the contents of our plate really play a key role in this inert material? And conversely, can hair cosmetics (leave-ins, masks, serums, etc.) provide anything other than a bandage effect?

It's true that hair is a dead fiber once it emerges from the scalp. However, its quality and strength depend directly on the nutrients absorbed by the body during its growth. A diet rich in vitamins, minerals, and essential amino acids helps produce better-quality keratin and, therefore, stronger hair. As for hair care, its action goes beyond aesthetics: it protects the fiber, prevents breakage, and maintains moisture—a crucial point for textured hair.

Speaking of food, why don't you help us make our shopping list? 😊 Are there some foods that are better known than others for hair care? Come on, tell us your secrets! This might inspire some delicious hair-friendly dishes to cook in the coming days.

For strong and healthy hair, choose:

Proteins (eggs, fish, chicken, legumes) to boost keratin production.

Good fats (avocado, olive oil, walnuts, almonds) to nourish the hair fiber and scalp.

Iron and zinc (lentils, spinach, seafood) to promote growth and limit hair loss.

Vitamin C (kiwi, citrus fruits, peppers) which helps to bind iron and stimulate blood circulation in the scalp.

Omega-3 (salmon, flax seeds) for hair suppleness and strength.

Okay, now that we have a nice, varied and filling plate... At what point in our lives might it be worthwhile to supplement? I imagine there are times when our hair might be going through a real existential crisis and need a little "pick-me-up"...

There are several key periods when hair can become weakened:

After pregnancy, when the hormonal drop causes significant hair loss.

During seasonal changes, particularly in autumn and spring, hormonal fluctuations and accumulated fatigue disrupt the hair cycle, promoting hair loss.

In times of stress or fatigue, which slow down growth and increase breakage.

When eating an unbalanced diet or one lacking in essential nutrients, this weakens the hair.

In these cases, targeted supplementation can really make a difference by providing the nutrients necessary for healthy hair growth.

The right choice: Pousse & Volume capsules (awarded at the Victoires de la Beauté 2021-2022), formulated with a synergy of rosemary, nettle, field horsetail, grape seed extract, vitamins B5, B6 and B8, ginseng and zinc. Swallow two capsules per day for 3 months.

So, this is the context in which your hair growth capsules/gummies, for example, can be found. We know that you collaborate with a renowned French laboratory to develop your formulas, which have earned you several prestigious awards (including the famous Victoires de la Beauté). What explains the strength and success of your internal cures?

Our treatments are designed in partnership with a renowned French laboratory, with formulas highly concentrated in scientifically validated active ingredients. We leave no room for chance: each ingredient is scrupulously selected for its effectiveness, optimal dosage, and synergy with the other components of the formula.

What makes a good treatment so effective is not only the presence of beneficial active ingredients, but also their precise dosage. An under-dosed active ingredient won't be able to deliver all of its benefits. That's why we make sure to incorporate optimal concentrations to guarantee visible and lasting results.

At In Haircare , we refuse to compromise between natural and high-performance. Our formulas combine plants, vitamins, and minerals to work deep down and provide the perfect balance between nutrition and hair strengthening.

We know that textured hair has specific needs when it comes to hydration, nutrition, and strengthening the hair fiber. That's why we've incorporated targeted active ingredients into our treatments, capable of meeting the specific needs of curly, coily, and frizzy hair. But our formulas remain universal: although they were designed primarily for textured hair, they are perfectly suited to all hair types, providing the lengths and scalp with essential nutrients to strengthen them from within.

It is this high standard and tailor-made approach that has allowed us to be rewarded with several prizes, including the Victoires de la Beauté, and which today make the difference within our community.

The right choice: Pousse & Volume gummies (awarded at the Victoires de la Beauté 2021-2022), formulated with a rocket-apple-flavored cocktail, vitamins C, E, B5, B6, B8, B9, B12, and zinc. Chew 2 gummies per day.

The hair supplement market is booming, with increasingly sophisticated active ingredients (collagen, keratin, biotin, etc.). The problem: there's sometimes doubt about our body's ability to absorb them. How can we separate the wheat from the chaff in a booming market, inevitably tempted to ride the wave at the expense of performance?

It is essential to check:

Composition: favor formulas without unnecessary additives, with recognized active ingredients.

Bioavailability: Certain ingredients, such as biotin or zinc, must be in forms that are easily assimilated by the body.

The right dosage and synergy of ingredients: an effective supplement must contain optimal quantities and combinations of active ingredients that reinforce each other, such as zinc with biotin.

Brand transparency: certifications, clinical tests and labels are good indicators of quality.

Testimonials and opinions from users who have completed a complete treatment.

There's choosing the right supplement, but there's also the art and method of consuming it. What are the dos and don'ts for maximizing the benefits of an internal treatment? There must be some common rules for all hair problems and all hair types.

✅ Do:

Be consistent: The key to an effective treatment is consistency. Take your supplements every day, at the same time, to maximize their benefits.

Drink plenty of water: good hydration allows for better assimilation of active ingredients and promotes scalp health.

Accompany the intake with a balanced meal: certain nutrients, such as fat-soluble vitamins, are better absorbed in the presence of fat.

Follow a treatment course of at least 3 months: the hair cycle is long, and it takes time to see visible and lasting results.

❌ Don't:

Skipping days: Regularity is essential, otherwise the effects may be less than optimal.

Double the dose thinking it will speed up the results: hair grows at its own pace, and an excess of certain nutrients can be counterproductive.

Neglecting your diet and hydration: a treatment works in addition to a healthy lifestyle, not as a replacement.

Stopping too early: it often takes several weeks to see a real difference, patience is required!

We chat, we chat... We almost forget the other side of the coin: the "out"! Many of us are sure we have this phase under control (shampoo, conditioner, mask, leave-in, etc.). And yet, I'm sure you hear a lot of misinformation circulating on social media and in salons. What are the worst ones that we should all skip from our routines?

“Hair gets used to the products and stops reacting”: No, it’s more the hair’s needs that change over time.

"Oil moisturizes hair": False, oil does not moisturize, it nourishes the hair fiber and seals in the moisture already present, thus preventing water from evaporating. To moisturize hair, you must first use a water-based treatment like a leave-in or a moisturizing spray.

The right choice: Milk'In, the brand's iconic leave-in milk! Formulated with a blend of upcycled rice water, bamboo milk, and organic flaxseed oil, it moisturizes the hair fiber and makes detangling easier. If you have curly hair, use it to restore tone to your curls.

And conversely, I'm convinced there's at least one care routine we all overlook for the health and beauty of our hair. We're very curious to get a professional's opinion on what we sometimes take for simple fads with a placebo effect. Revelation in 3… 2… 1…

Scalp massage! It stimulates blood circulation, promotes hair growth, and helps distribute sebum more evenly. Just a few minutes a day are enough to have a visible impact on hair health.

The right choice: Detox Jelly , an exfoliating treatment to use once a week, just before shampooing. Its fine sea salt crystals lift away impurities, dead cells and product residue that "suffocate" the roots while stimulating the natural activity of the hair bulb. It's your chance to boost your vigor and feel perfectly clean!

I'd like to dedicate a paragraph to one of your star products, which is out of stock on your website as we speak: Miracle Oil, a fortifying and nourishing treatment that was voted best oil at the Natural Hair Academy (NHA) 2023. Its formula comes from a recipe passed down from mother to daughter. What role do traditional natural "remedies" play in your R&D?

At In Haircare , traditional natural remedies are a source of inspiration in our research and development approach. Miracle Oil, currently out of stock, is the perfect example. It draws its strength from Carapate oil, an active ingredient known for its fortifying properties, widely used in traditional hair care in the Antilles. But our DNA is not based solely on tradition: we combine these active ingredients with innovative and equally effective ingredients, to take the performance of our treatments even further. It is this alliance between tradition and innovation that defines our products and guarantees their effectiveness.

The right choice: the famous Miracle Oil, of course! The brand's go-to for brittle hair, it helps strengthen the hair fiber from root to tip thanks to its powerful toning and revitalizing action on the scalp. It's effective from the first application.

“Hair gets used to the products and stops reacting”: No, it’s more the hair’s needs that change over time.

And speaking of grandmother's remedies for hair... What are the essentials that you don't hesitate to recommend to your clients? The ones that you apply daily to boost your hair by focusing on the simplicity and accessibility of the ingredients?

Among the essential grandmother's remedies for hair care, Carapate oil is a classic. It was often combined with honey and egg yolk to create a nourishing mask, ideal for strengthening and softening the hair fiber.

Here is a recipe inspired by this traditional treatment:

1 tablespoon of Miracle Oil (nourishes and strengthens)

1 tablespoon of honey (hydrates and softens)

1 egg yolk (strengthens hair fiber)

Apply this mixture to dry or slightly damp hair, leave on for 30 minutes under a warm towel, then rinse with a mild shampoo.

Although your range is designed for everyone, you specifically cater to textured hair, whose specific needs you are well-versed in thanks to your visionary success with the Ma Coiffeuse Afro platform. How do their needs differ from those of Caucasian or Asian hair?

Textured hair (curly, coily, and kinky) has a specific structure that makes it more fragile and prone to dryness. Unlike Caucasian or Asian hair, its coiled shape prevents sebum from naturally distributing along its entire length, making it more vulnerable to breakage and frizz.

They therefore require highly hydrating and nourishing care, a routine that preserves their elasticity and definition, and special attention to sealing in moisture. Our formulas have been developed with these specific needs in mind, favoring ultra-nourishing and protective active ingredients adapted to textured hair.

Curly hair, in fact, is generally the first to fear frizz and dryness. What In Haircare routine could you recommend to restore softness and tame those unruly locks, especially when humidity gets in the way (and tangles)?

For well-defined and bouncy curls, here is the ideal routine with In Haircare :

1. Deep hydration: Apply Milk'In to damp hair to intensely nourish the lengths and prevent dryness. Its lightweight texture penetrates the hair fiber without weighing down curls.

2. Curl definition: Use Curl N'Go Styling Jelly by scrunching the lengths to create beautiful, well-defined, and flexible curls.

3. Protection and support: use the plopping technique with a cotton t-shirt or a microfiber towel to absorb excess water and set the curls without breaking them.

4. Nighttime care: Sleep with a satin bonnet or silk pillowcase to limit friction, preserve moisture and prevent frizz when you wake up.

With this routine, curls stay supple, well-nourished and defined for several days, even in the face of humidity!

The right choice: Curl N'Go styling jelly, your essential for long-lasting, bouncy curls. A guaranteed glowing effect on your locks thanks to its radiance-boosting formula enriched with provitamin B5 and rice protein.

Any last words of advice? A witty remark? A wink? An inspiring quote? A teaser? A love note? We'll give you carte blanche. 😉

Your hair is a reflection of the love you have for it. Take care of it, listen to it, pamper it... and it will repay you a hundredfold!
