Discover Natural Formula — Israel's leading professional hair care brand. Keratin treatments, curly hair products, color shampoos, moisturizers and more. Shipped directly from Israel to the USA. Shop now at KosherTop.

If you've spent time in an Israeli hair salon, you've almost certainly encountered Natural Formula.

It's the brand that Israeli hairdressers recommend. The one that Israeli women with curly hair swear by. The one that women who've invested in keratin straightening treatments use to protect their results — because they've learned that ordinary shampoo undoes in three washes what the salon spent two hours doing.

Natural Formula is one of Israel's most respected professional hair care brands, built on the understanding that different hair types need genuinely different formulations — not marketing language, but actual different chemistry. And now, for the first time, the full Natural Formula range is available to order directly from Israel to the USA through KosherTop.

Here is the complete guide to every Natural Formula product available — organized by hair type, so you can find exactly what your hair needs.

The Natural Formula Philosophy — Why Israeli Women Trust It

Natural Formula was built around a simple but rarely honored principle in the hair care industry: the products on your shelf should match your actual hair type, not a category that's broad enough to include everyone and specific enough for no one.

The result is a range organized around what hair actually does — how it behaves after chemical treatments, how it responds to humidity, what it needs when it's been heat-styled repeatedly, what curls need that straight hair doesn't. Every formula in the Natural Formula range is built for a specific need, with ingredients selected to address that need rather than to smell nice and feel pleasant in the shower.

For women who have been buying American drugstore brands and wondering why their hair never quite looks the way it should — Natural Formula is often the answer.

For Keratin-Treated & Straightened Hair — The Keratin Intense Series

Keratin straightening is one of the most popular salon treatments in Israel — and one of the most commonly undermined by the wrong shampoo. Standard shampoos contain sodium chloride (salt), which actively breaks down keratin bonds and shortens straightening results from months to weeks.

Natural Formula's Keratin Intense series was built specifically to solve this problem.

Keratin Intense Shampoo — Salt-Free Keratin Repair

<cite index="50-1">Specially developed to care for hair damaged by chemical straightening treatments and frequent heat styling. The advanced keratin complex helps rebuild the internal hair structure while forming a protective smoothing layer along the hair fiber. Helps maintain straightening results up to 3x longer. Salt-free formula — no sodium chloride — helps preserve keratin and chemical straightening results while protecting hair from breakage, heat, and environmental stress. 400ml.</cite>

For anyone who has invested in a keratin treatment and wants to protect that investment, this shampoo is non-negotiable. The salt-free formula alone extends the life of straightening results significantly — something most women don't discover until they've already shortened their treatment by several weeks.

Hair type: Straightened, heat-styled, chemically treated, damaged Key benefit: Maintains straightening results up to 3x longer

Keratin Intense Conditioner — Deep Keratin Restoration

<cite index="57-1">The conditioner maintains straightening results through a double keratin formula — rebuilds the inside of the hair and creates an outer protective coating that envelops and smooths the hair along its entire length. Maintains smoothing results 3x longer. Enriched with panthenol that strengthens the action of keratin. 400ml.</cite>

Used together with the Keratin Intense Shampoo, the conditioner completes the repair cycle — the shampoo rebuilds the structure, the conditioner seals and protects it. Used alone after a regular shampoo, it adds significant hydration and smoothness.

Hair type: Straightened, heat-damaged, dry, brittle Key benefit: Seals and protects the hair fiber after keratin rebuilding

Keratin Water Treatment — 9-Second Hair Repair

<cite index="58-1">A fast-acting hair repair treatment ideal for hair that undergoes frequent blow-drying or flat-iron styling. Helps maintain long-lasting smooth results while keeping hair hydrated and revitalized. Applied after shampooing, before conditioner or mask. Sulfate-free formula. 200ml.</cite>

This is the product for women who style with heat daily and need fast, effective protection that doesn't slow down the morning routine. Nine seconds of application between shampoo and conditioner — that's the entire time investment. The result is hair that withstands heat styling better and retains moisture through the day.

Hair type: Frequently heat-styled, straightened, damaged Key benefit: Fast-acting repair that fits into any routine

Keratin Intense Shampoo (Original SLS-Free Formula)

<cite index="52-1">Pure keratin shampoo for straightened or styled hair that restores, nourishes and strengthens. Without salts — maintains straightening results 3x longer. Rebuilds the inside of the hair and creates an outer protective coating. Increases hair resistance to breakage, heat damage and chemicals. 400ml.</cite>

The original Keratin Intense formula — slightly different formulation from the newer version, same core benefit. If your hair has been seriously damaged by repeated chemical treatments, this formula's intensive approach makes the difference.

Keratin Anti-Dandruff Shampoo — Two Problems, One Formula

<cite index="62-1">Anti-dandruff keratin shampoo specially developed to cleanse the scalp thoroughly and help prevent the formation of new dandruff. Formulated to repair, nourish and strengthen hair weakened by chemical straightening treatments or frequent heat styling. The gentle salt-free formula helps maintain the results of hair straightening treatments while restoring softness, elasticity and shine. After each wash, hair feels clean, refreshed and free from dandruff, while appearing smoother, stronger and healthier with radiant shine. 400ml.</cite>

For women who deal with both the aftermath of keratin treatments and scalp sensitivity or dandruff — a combination that most shampoos can't address simultaneously — this is the product that handles both without compromising on either.

Hair type: Straightened hair with dandruff-prone scalp Key benefit: Dandruff control without breaking down keratin treatment

For Curly & Wavy Hair — The Curly Girl Series

Curly hair needs different chemistry than straight hair. It needs products that define without weighing down, hydrate without making the curl sticky, and hold without creating build-up. Natural Formula's curly hair range was developed with the Curly Girl Method in mind — one of the most carefully researched approaches to curly hair care in the world.

Curly Hair Conditioner — CG Method Approved

<cite index="54-1">Specially developed for wavy to curly hair and fully compatible with the Curly Girl (CG) Method. Free from silicones, sulfates, parabens, mineral oil and phthalates. Provides gentle conditioning that helps maintain curl structure while improving softness, flexibility and manageability. Enriched with babassu, castor, moringa and coconut oils. 400ml.</cite>

The Curly Girl Method has a devoted following for a reason: it works. And the reason most CG-compatible conditioners work so well is that they're formulated without the ingredients — silicones, sulfates — that block moisture and disrupt curl structure in the first place. Natural Formula's CG conditioner delivers this approach with Israeli-quality formulation.

Hair type: Wavy, curly, textured CG Method: Fully compatible

Keratin Curl Cream — Defined Curls Without the Frizz

<cite index="63-1">Professional styling cream enriched with pure keratin to help smooth and support the hair fiber while enhancing soft, natural-looking curls. Designed to create more open, relaxed curls. Helps reduce volume and frizz. Strengthens and supports hair structure. Provides hydration and softness. Enhances natural shine. Free from parabens, sulfates and sodium chloride. 400ml.</cite>

The combination of keratin and curl-defining cream is Natural Formula's answer to a question every curly-haired woman has: how do I get defined curls that don't look frizzy, don't feel crunchy, and don't weigh my hair down? The keratin strengthens the hair fiber; the cream defines the curl pattern; the result is curls that look intentional rather than accidental.

Hair type: Curly, wavy, frizzy Key benefit: Keratin + curl definition in one product

Aqua Light Moisturizer for Curly Hair — Water-Based, No Grease

<cite index="47-1">Light water-based moisture for styling curls without a greasy feeling. For curly hair that dries quickly and loses its vitality. The light moisture of Natural Formula based on water nourishes the curls without feeling greasy. Dries quickly. 400ml.</cite>

The most common complaint about curl moisturizers: they make hair feel heavy, oily, or coated. Aqua Light solves this with a water-based formula that hydrates without weight. The curl gets moisture; the scalp doesn't get grease.

Hair type: Curly hair that needs moisture without heaviness Key benefit: Water-based hydration that doesn't weigh curls down

Design Moisturizing Cream for Wavy to Curly Hair

<cite index="45-1">Styling moisturizer with a light gel texture for wavy to curly, dry and wild hair. Shapes and fixes the curls for long hours without burdening. 400ml.</cite>

For the woman whose hair sits between wavy and curly — the type that can't decide what it wants to do — the Design Moisturizer provides enough hold to define the wave pattern while keeping the texture soft and natural-looking.

Hair type: Wavy to curly, dry, frizzy Key benefit: Lightweight hold that defines without stiffening

For Dry & Damaged Hair — Deep Nourishment

Oil Nutrition Moroccan Argan Moisturizer — For Very Dry Hair

<cite index="60-1">Nourishing moisture with Moroccan argan oil to restore moisture for very dry and damaged hair. The nourishing moisture contains Moroccan argan oil rich in vitamin E and omega 3, 6, 9 essential fatty acids. Also enriched with shea butter, olive and sunflower oils, honey and propolis extracts that give the hair a deep nourishment that is quickly absorbed and does not burden the hair. After application, the hair is soft and supple, comfortable to style and radiates a healthy shine. 400ml.</cite>

Argan oil is genuinely one of the most effective ingredients for very dry hair — not because of marketing, but because its composition of vitamin E and essential fatty acids penetrates the hair shaft rather than simply coating the surface. Combined with shea butter, olive oil, and honey in Natural Formula's formulation, the result is a moisturizer that actually reaches the parts of the hair that need it most.

Hair type: Very dry, damaged, dull, brittle Key benefit: Deep nourishment with argan oil that penetrates rather than coats

Aqua Light Moisturizer for Dry Hair — Honey-Enriched Hydration

<cite index="41-1">For hair that is brittle, lacks shine and vitality. The natural moisture of Natural Formula is not oily, does not weigh down and gives the hair instant moisture. Enriched with honey extract. 400ml.</cite>

For dry hair that needs moisture but not weight — the Aqua Light for dry hair delivers immediate hydration with honey extract, leaving hair soft and manageable without the heavy, coated feeling of heavier treatments.

For Colored Hair — The Color Intense Series

Color Intense Shampoo — Deep Black

<cite index="55-1">Based on Pigment Booster technology to refresh and strengthen black hair color and enhance shine between salon visits. Recommended for use once a week or as needed. Does not cover graying hair. 250ml.</cite>

For women with black or dark brown hair: color fades between salon visits, and most shampoos accelerate the process. Natural Formula's Color Intense Deep Black uses Pigment Booster technology to actively refresh the color deposit in the hair, keeping black hair looking richly dark between dyeing sessions rather than fading toward a muddy brown.

Hair type: Dyed black or dark brown hair Key benefit: Refreshes and intensifies black pigment between salon visits

🛒 Order Color Intense Deep Black →

Color Intense Shampoo — Wild Red

<cite index="56-1">Based on Pigment Booster technology to refresh and strengthen red hair color and enhance shine between dyeing. 250ml.</cite>

Red is the fastest-fading hair color — within weeks of a salon visit, red hair begins losing its vibrancy. The Color Intense Wild Red shampoo deposits red pigment with each wash, maintaining the richness of the color between appointments and extending the time between salon visits.

Hair type: Dyed red or copper hair Key benefit: Maintains red pigment intensity between salon visits

Silver Shampoo — Purple Shampoo for Blonde, Silver & White Hair

<cite index="53-1">Purple shampoo for blonde, silver and white hair. Yellow-tone neutralizing formula with keratin. Free from sodium chloride salt, parabens, hydrogen peroxide and ammonia. Apply to wet hair, lather and leave on for 2-3 minutes, then rinse thoroughly. Use once a week or as needed. For best results, follow with Silver Conditioner. 400ml.</cite>

Blonde, silver, and white hair develops yellow and brassy tones over time — caused by minerals in water, heat styling, and environmental exposure. Natural Formula's Silver Shampoo neutralizes these tones with purple pigment while the keratin formula strengthens the hair fiber. The result is hair that looks as bright and cool-toned after ten weeks as it did after one.

Hair type: Blonde, silver, white, highlighted Key benefit: Neutralizes brassiness while strengthening with keratin
