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

That's normal: most of these products absorb or mask the greasy look after the fact. Sudoblok acts 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 hot weather, under a cap, or during long, busy days.

2. Isn't aluminum on the scalp dangerous?

Sudoblok uses Aluminum Chlorohydrate, an antiperspirant active commonly used in cosmetics. The key difference: it's not an aerosol, but a cream applied directly to the skin, so there's no inhalation. On the scalp, apply a small amount, avoid the eyes, do not use on irritated skin, and discontinue use if a 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 sweat ducts, which washes out. The formula contains glycerin and is free of fragrance and dye. To avoid weighing hair down, start with a very small amount and apply only at the root. Do not apply on irritated, injured, or very sensitive scalp.

4. When exactly do 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, gently massage in, then style as usual. For intense days — heat, workouts, stress, events, hats — also apply before the activity. The 120 ml format lasts approximately 2 to 3 months with daily use on the scalp.

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

You're not alone. Many people plan their washes, hairstyles, or hat-wearing around a sweaty scalp. Sudoblok is designed to help you take back control — no heavy fragrance, no visible powder, and no sticky feeling. Apply in the morning, style your hair, and move on with your day.

How to Use

Apply a small amount to clean, dry scalp Create sections with a comb for even distribution Gently massage into the roots Allow to absorb, then proceed with styling Can also be applied to other areas prone to sweating Note: a little goes a long way — too much product may weigh hair down

Versatile

Traditional stick or spray antiperspirants are formulated for underarms, period. Sudoblok is designed for the areas where sweat really becomes a problem — including the scalp, where moisture quickly creates 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. For the scalp, something different was needed: a lightweight texture, easy to distribute at the roots, that dries quickly and is forgotten for the rest of the day.

Your Scalp Routine in 3 Steps.

Two minutes in the morning, a fresher scalp that lasts until evening.

01 — Separate

Title

After showering, create a few parts

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

02 — Apply

Title

A small amount at the roots

Apply a small amount to your fingertips, then gently massage into the scalp section by section. The 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; for heat, workouts, or hat wear, apply before the activity.

Fresh roots, real stories.

Marie-Hélène

I'm no longer afraid my hair will look greasy by noon.

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

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 showering. Part the hair into a few sections to target the roots.

❌

Do not apply on irritated, scraped, or sunburned scalp, after recent coloring, or immediately after a sensitizing treatment.

Step 2

✅

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

❌

Avoid using too much: a small amount on the scalp is all you need. More is not better and can weigh hair down.

Step 3

✅

One application in the morning helps cover the entire day. For very active days, heat, sports, or events, also apply before the activity.

❌

No 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 on multiple areas of the body, including the scalp. Unlike a styling product that absorbs or masks oily buildup, Sudoblok helps reduce sweat at the source thanks to its antiperspirant active ingredient, Aluminum Chlorohydrate.

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

Sudoblok is formulated 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 bothers you. A small amount is enough to cover a large surface.

3. Is it really different from a dry shampoo?

Yes. A dry shampoo absorbs excess sebum and gives a temporary clean effect, but it does not reduce scalp perspiration. Sudoblok is an antiperspirant: it helps form a temporary plug at the opening of the sweat ducts and reduces the amount of sweat produced for 24 to 48 hours.

4. Is the aluminum in it safe?

Yes, Aluminum Chlorohydrate is a commonly used antiperspirant active ingredient in cosmetics. Sudoblok is not an aerosol: it's a cream applied directly to the skin, so there's no inhalation involved. 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 clients notice a difference from the very first application. The full effect often develops within 3 to 5 days of regular use. If after one week you don't see any change, reach out to us — you're covered by our 60-day satisfaction guarantee.

6. Does it leave hair heavy or sticky?

No, as long as you use the right amount. The formula is dye-free and designed not to leave white residue or weigh hair down. The classic mistake is using too much — start with a very small amount, massage into the roots, then adjust as needed.

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

The formula contains no fragrance or dye, which significantly reduces the risk of irritation. For very reactive skin, do a patch test on a small area (inner arm) before the first full application. For pregnancy and breastfeeding, topical aluminum is considered safe by health authorities due to very low absorption, but as a precaution, we always recommend talking to 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 washing frequency. 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 questionnaire, no justification, no product to ship back. Just email us at [email address to insert] and we'll take care of everything.
