1. Will this actually work on my scalp? I've tried dry shampoo, frequent washing, mattifying powders... nothing lasts.

That's totally normal — most of those products absorb or mask oiliness after the fact. Sudoblok works before, by helping reduce perspiration at the source. Less moisture at the scalp means roots that stay looking fresher, longer. Most clients notice a difference from the very first applications, especially in the heat, under a hat, or during long, busy days.

2. Isn't aluminum on the scalp dangerous?

Sudoblok uses Aluminum Chlorohydrate, an antiperspirant active commonly found in cosmetic products. The key difference: it's not an aerosol — it's a cream applied directly to the skin, so there's no risk of inhalation. On the scalp, apply a small amount, avoid the eye area, do not use on irritated skin, and discontinue use if any reaction occurs.

3. Will it clog my pores, dry out my scalp, or weigh down my hair?

Sudoblok helps form a temporary plug at the opening of the sweat ducts, which washes away with shampooing. The formula contains glycerin and is free of fragrance and dyes. To avoid weighing hair down, start with a very small amount and apply only at the roots. Do not apply on irritated, damaged, or highly sensitive scalps.

4. When exactly should I apply it, and how many times a day?

Apply it in the morning on a clean, dry scalp. Part your hair into sections, apply a small amount at the roots, massage gently, then style as usual. On big days — heat, workouts, stress, events, hats — apply before the activity too. The 120 ml format lasts roughly 2 to 3 months with daily use on the scalp.

5. At work, at the gym, or out with friends, my roots get greasy fast. Will I really be able to stop worrying about it?

You're not alone. A lot of people plan their wash days, hairstyles, or hat-wearing around a sweaty scalp. Sudoblok is designed to help you take back control — no heavy fragrance, no visible powder, no sticky residue. Apply it in the morning, style your hair, and get on with your day.

How to Use

Apply a small amount to a clean, dry scalp. Use a comb to create sections and distribute evenly. Gently massage into the roots. Allow it to absorb, then style as usual. Can also be applied to other sweat-prone areas. A little goes a long way — using too much may weigh hair down.

Versatile

Traditional stick or spray antiperspirants are formulated for underarms — full stop. Sudoblok is designed for the areas where sweat really becomes a problem, including the scalp, where moisture quickly leads to a greasy, uncomfortable feel.

Classic antiperspirant

Designed in Quebec, for scalps that sweat more than they should.

Stick and spray antiperspirants were designed for underarms. Your scalp needed something different: a lightweight texture that's easy to apply at the roots, dries quickly, and disappears for the rest of the day.

Made in Quebec

Your scalp care routine in 3 simple steps.

Two minutes in the morning, a fresher scalp that lasts all day.

01 — Separate

Title

After showering, create a few parts

On a clean, dry scalp, create a few sections with your fingers or a comb. Sudoblok is applied directly at the root, right where sweat and oiliness begin.

02 — Apply

Title

A small amount at the roots

Apply a small amount to your fingertips and gently massage into the scalp section by section. The lightweight texture absorbs quickly, with no heavy fragrance or sticky finish.

03 — Style

Title

Style it, then forget it.

Once Sudoblok is absorbed, style your hair as usual. A single morning application helps keep roots fresher throughout the day. Before workouts, heat exposure, or wearing a hat, apply beforehand for best results.

Fresh roots, real stories.

Marie-Hélène

I no longer worry about my hair looking greasy by noon.

Before Sudoblok, my roots would get greasy just hours after washing. Now, my scalp stays fresher for longer and I no longer feel like I need to hide my hair by the end of the day.

My boyfriend keeps stealing my bottle.

I bought it for my roots that get greasy way too fast. My boyfriend tried it before the gym under his cap, and now he wants his own bottle. We keep one in the bathroom and one in the gym bag.

How to use Sudoblok on the scalp.

Three simple steps for fresher roots from morning to night.

Step 1

✅

Apply a small amount to a clean, dry scalp — ideally in the morning after your shower. Part your hair into a few sections to target the roots directly.

❌

Do not apply on an irritated, scratched, or sunburned scalp, after a recent colour treatment, or immediately after a sensitizing treatment.

Step 2

✅

Gently massage with your fingertips to distribute evenly. Allow it to absorb before applying your styling products or putting on a hat.

❌

Don't overdo it — a small amount on the scalp is all you need. Using more than necessary can weigh hair down.

Step 3

✅

One application in the morning is enough to keep you covered all day. For extra-active days, heat, workouts, or events, apply again before the activity.

❌

You don't need to apply it morning and night — let your scalp breathe overnight and wash your hair according to your usual routine.

Frequently Asked Questions

1. What exactly is Sudoblok?

Sudoblok is a versatile antiperspirant made in Quebec, designed to temporarily reduce perspiration across multiple areas of the body, including the scalp. Unlike styling products that absorb or mask oily buildup, Sudoblok helps reduce sweat at the source thanks to its active antiperspirant ingredient, Aluminum Chlorohydrate.

2. What areas of the body can I apply it to?

Sudoblok is designed to be versatile. You can use it on your scalp when roots get oily or damp quickly, but also on your feet, hands, underarms, face, or any area where perspiration is a concern. A small amount goes a long way.

3. Is it really different from a dry shampoo?

Yes. Dry shampoo absorbs excess oil and gives a temporarily clean look, but it doesn't reduce scalp perspiration. Sudoblok is an antiperspirant: it helps form a temporary plug at the opening of the sweat ducts, reducing the amount of sweat produced for 24 to 48 hours.

4. Is the aluminum in it safe?

Yes, Aluminum Chlorohydrate is a common antiperspirant active ingredient widely used in cosmetics. Sudoblok is not an aerosol — it's a cream applied directly to the skin, so there's no risk of inhalation. As with any product applied near the face and hair, avoid contact with the eyes and discontinue use if irritation occurs.

5. How long before I see results?

Most customers notice a difference after the very first application. The full effect typically develops within 3 to 5 days of regular use. If you don't see any change after a week, reach out to us — you're covered by our 60-day satisfaction guarantee.

6. Does it leave hair feeling heavy or sticky?

No, as long as you use the right amount. The formula is dye-free and designed to leave no white residue or weigh hair down. The classic mistake is using too much — start with a very small amount, massage it into the roots, then adjust as needed.

7. Is it suitable for sensitive skin, during pregnancy, or while breastfeeding?

The formula is free of fragrance and dyes, which significantly reduces the risk of irritation. If you have highly reactive skin, do a patch test on a small area (like the inside of your arm) before your first full application. As for pregnancy and breastfeeding, aluminum in topical use is considered safe by health authorities due to its very low absorption rate — but as a precaution, we always recommend checking with your doctor or midwife before starting any new product.

9. How long does a bottle last and where is it made?

Sudoblok is 100% made in Quebec. The 120 ml format lasts an average of 2 to 3 months with daily use on the scalp, depending on the amount used and how often you wash your hair. Store at room temperature, away from direct light and extreme heat.

10. What if Sudoblok doesn't work for me?

You have 60 days to try it. If you're not satisfied for any reason, we'll give you a full refund — even if the bottle has been opened. No questionnaires, no justification needed, and no product to ship back. Just reach out to us at [email address to insert] and we'll take care of everything.
