Lotion P50 Capillaire

EXFOLIATING + REBALANCING SCALP LOTION

Biologique Recherche Lotion P50 Capillaire brings the iconic P50 exfoliating philosophy to the scalp.

Designed for all Scalp Instants and particularly suited to scalps prone to excess sebum, its targeted formula helps remove accumulated residue and surface buildup while regulating excess oil and restoring a cleaner, more balanced scalp environment.

The scalp is skin — and just like the skin on the face, it can accumulate sebum, dead surface cells, styling-product residue and environmental debris.

Lotion P50 Capillaire helps reset that environment through gentle chemical exfoliation, leaving the scalp feeling fresher, cleaner and better prepared for the shampoo, mask or treatment that follows.

Scalp Instant:

Recommended for all Scalp Instants, particularly those prone to seborrhea or excess sebum.

Especially useful when the scalp is experiencing:

• Excess oil or rapid regreasing
• Product buildup
• Visible flakes or scales
• Dandruff-prone conditions
• An itchy-feeling scalp
• Congestion
• Dry or uneven scalp texture
• A scalp that feels heavy or coated
• Frequent use of dry shampoo or styling products
• A need for deeper scalp preparation before treatment

Benefits:

• Gently exfoliates the scalp
• Helps remove accumulated residue and dead surface cells
• Helps regulate excess sebum
• Supports a cleaner, more balanced scalp
• Helps reduce the appearance of flakes and scales
• Helps relieve the feeling of an overloaded scalp
• Purifies without relying solely on aggressive shampooing
• Prepares the scalp for shampoos, masks, serums and targeted treatments
• Supports an optimal environment for healthy-looking hair

Why Should You Exfoliate Your Scalp?

We exfoliate the face.

We exfoliate the body.

But the scalp is often forgotten.

The scalp is constantly exposed to:

• Sebum
• Sweat
• Shampoo and conditioner residue
• Dry shampoo
• Styling products
• Environmental debris
• Heat from styling tools
• Changes in temperature

Over time, these can accumulate at the surface and make the scalp feel oily, itchy, flaky or simply unbalanced.

Exfoliating scalp care helps remove this excess residue and dead surface buildup so the scalp can maintain a cleaner, more balanced environment.

This is the role of Lotion P50 Capillaire.

Think of it as skincare for the scalp rather than another hair styling product.

Oily Hair vs. Oily Scalp: Why It Matters

When hair becomes greasy quickly, the problem usually begins at the scalp.

Sebaceous glands located around the hair follicles produce sebum to protect and lubricate the scalp and hair.

Sebum itself is essential.

The issue is excess sebum.

When production becomes excessive, you may notice:

• Roots becoming oily quickly
• Hair losing volume
• A scalp that feels coated
• More frequent washing
• Product buildup becoming increasingly noticeable

This is why repeatedly using stronger shampoo is not necessarily the answer.

Lotion P50 Capillaire takes a scalp-first approach by helping regulate excess sebum while exfoliating accumulated surface residue.

How to Use:

1. Apply Lotion P50 Capillaire directly to a dry scalp, working section by section.
2. Massage gently using the fingertips.
3. There are two ways to incorporate it:

As a leave-on scalp lotion:
Apply evenly and massage gently. Do not rinse.

Before shampooing:
Apply to the dry scalp, massage gently and leave on for 5 to 10 minutes before shampooing.

• Avoid aggressive scratching or vigorous massage.
• Avoid contact with the eyes.
• Avoid direct sun exposure immediately after application.
• Do not apply to scratched, irritated or compromised scalp skin.
• Do not use on children.
• For external use only.

Loshen & Crem’s Recommendation:

Lotion P50 Capillaire is one of the Biologique Recherche products we think people understand immediately once we ask one question:

“When was the last time you treated your scalp like skin?”

We think about it when someone tells us:

• “My roots get oily the day after washing.”
• “I use so much dry shampoo.”
• “My scalp always feels like it has buildup.”
• “I have flakes even though I shampoo regularly.”
• “My scalp gets itchy.”
• “My hair never feels truly clean at the roots.”
• “I use a lot of styling products.”

This doesn't necessarily mean you need to wash your hair more often.

Sometimes the scalp itself needs a more targeted exfoliating and rebalancing step.

We particularly like Lotion P50 Capillaire before shampooing because it gives the formula dedicated contact time on the scalp before everything is cleansed away.

And one very important thing:

Don't scrub.

The acids are already doing the exfoliating work.

Use your fingertips gently and let the formula do its job.

Lotion P50 Capillaire vs. Clarifying Shampoo

They are not the same thing.

A clarifying shampoo primarily cleanses the hair and scalp by removing oils and product residue during washing.

Lotion P50 Capillaire is a targeted scalp treatment applied directly to the scalp to:

• Exfoliate
• Help regulate excess sebum
• Remove accumulated surface residue
• Rebalance the scalp

Think:

• Clarifying shampoo = deeper cleansing wash
• Lotion P50 Capillaire = targeted scalp exfoliation + regulation

The two can sometimes complement one another, but they do different jobs.

Lotion P50 Capillaire vs. Facial Lotion P50

They share the P50 philosophy, but they are not interchangeable.

Facial Lotion P50 is formulated specifically for facial Skin Instants.

Lotion P50 Capillaire contains ingredients and an application method specifically adapted to the scalp.

Think:

• Lotion P50 → facial skin
• Lotion P50 Capillaire → scalp

Do not use Lotion P50 Capillaire as a substitute for your facial Lotion P50.

Does Lotion P50 Capillaire Help an Oily Scalp?

This is one of its primary uses.

Biologique Recherche specifically recommends Lotion P50 Capillaire for all Scalp Instants but notes that it is especially suited to Scalp Instants prone to seborrhea.

The formula helps regulate excess sebum while exfoliating accumulated surface residue.

If your roots become oily very quickly after washing, this is one of the Biologique Recherche scalp treatments we would consider.

Lotion P50 Capillaire + Dandruff or Flakes

Biologique Recherche identifies dandruff, hyperseborrhea, sensitivity and dryness as situations where scalp exfoliation may be beneficial.

Lotion P50 Capillaire helps exfoliate and remove visible surface scales and residue.

However, not every flaky scalp is the same.

Flakes may be related to:

• Excess oil
• Dryness
• Product buildup
• Irritation
• Dandruff
• Other scalp conditions

If flaking is persistent, significant or accompanied by pronounced redness, soreness or hair loss, we recommend appropriate professional assessment rather than assuming stronger exfoliation is the answer.

Lotion P50 Capillaire + Dry Shampoo Buildup

If dry shampoo is part of your weekly routine, scalp buildup can accumulate more quickly.

Powders, starches, styling products and sebum can collect near the roots and make the scalp feel coated even after regular washing.

Lotion P50 Capillaire can be particularly useful as a pre-shampoo scalp reset to help loosen and remove accumulated surface residue before cleansing.

Can Lotion P50 Capillaire Help an Itchy Scalp?

Biologique Recherche specifically describes the product as helping reduce scalp itching.

However, itching has many possible causes.

If itching is persistent, severe or accompanied by broken skin, significant redness or other symptoms, avoid repeatedly exfoliating the area and have the scalp assessed appropriately.

Ingredients:

• Lactic Acid: An alpha-hydroxy acid that helps exfoliate accumulated dead surface cells from the scalp.
• Sodium Salicylate: A salicylate included within the exfoliating and purifying P50 formula.
• Citric Acid: Supports the multi-acid exfoliating complex.
• Vinegar (Acetum): Part of the characteristic P50-inspired rebalancing formula.

Does Lotion P50 Capillaire help dandruff?

Lotion P50 Capillaire helps remove scales and accumulated surface residue.

Persistent dandruff may have several underlying causes, so significant or recurring flaking should be assessed appropriately.

Does Lotion P50 Capillaire help flakes?

The cause of flaking still matters, particularly if the scalp is highly irritated or compromised.

Does Lotion P50 Capillaire help an itchy scalp?

Biologique Recherche specifically states that Lotion P50 Capillaire helps reduce itching.

If itching is severe, persistent or associated with scratched or irritated skin, do not continue applying active exfoliation without appropriate assessment.

Does Lotion P50 Capillaire help product buildup?

Yes. Scalp exfoliation helps remove residue from haircare and styling products, making it particularly interesting for clients who frequently use dry shampoo, styling products or heavier scalp treatments.

Should I use Lotion P50 Capillaire before or after shampoo?

It can be used either as a leave-on scalp lotion or before shampooing.

When using it before shampooing, Biologique Recherche recommends leaving it on for 5 to 10 minutes before washing the hair.

Do I rinse Lotion P50 Capillaire out?

• Not necessarily.
• Biologique Recherche's standard application says not to rinse.
• If you prefer to follow with shampoo, leave it on for 5 to 10 minutes first.

Should Lotion P50 Capillaire be applied to wet or dry scalp?

Apply it to a dry scalp, section by section.

Can I use Lotion P50 Capillaire every day?

Biologique Recherche's current consumer directions do not prescribe one universal frequency for every scalp.

Because it contains exfoliating acids, we prefer adjusting frequency according to your Scalp Instant and tolerance rather than assuming daily use is appropriate for everyone.

Can I use Lotion P50 Capillaire if my scalp is sensitive?

Biologique Recherche discusses scalp sensitivity as one of the situations where appropriate scalp exfoliation can be useful.

However, do not apply Lotion P50 Capillaire to scratched or irritated skin.

If your scalp is highly reactive, we recommend speaking with our team before introducing an exfoliating treatment.

Can I use Lotion P50 Capillaire on a dry scalp?

Biologique Recherche notes that exfoliating scalp treatments may also be relevant when dryness contributes to buildup and scaling.

Dryness and dandruff are not necessarily the same thing, so understanding the cause of your flakes is important.

Can I use Lotion P50 Capillaire on color-treated hair?

The product is applied primarily to the scalp rather than used as a traditional hair cleanser.

If you have recently coloured or chemically treated your hair and scalp, we recommend confirming timing with your colourist or our team before introducing an acid-based scalp treatment.

Does Lotion P50 Capillaire help hair growth?

Its primary role is scalp exfoliation, sebum regulation and rebalancing.

A cleaner, balanced scalp provides a healthier environment for the hair, but we would not position Lotion P50 Capillaire as a hair-growth treatment.

Can I use Lotion P50 Capillaire with dry shampoo?

Yes — and we particularly like it when dry shampoo buildup is part of the concern.

Use Lotion P50 Capillaire as a scalp-focused treatment to help remove accumulated residue before your next shampoo.

Can I massage Lotion P50 Capillaire with the Mini Gant?

Biologique Recherche's current official directions recommend gentle fingertip massage.

At Loshen & Crem, we would keep the application simple and avoid aggressive physical exfoliation, particularly because the formula already contains exfoliating acids.

Can I use Lotion P50 Capillaire on irritated or scratched scalp skin?

No.

Biologique Recherche specifically advises against applying the product to scratched or irritated skin.

Do I need sun protection after using Lotion P50 Capillaire?

Biologique Recherche advises avoiding direct sun exposure immediately after application.

This is particularly relevant if areas of the scalp are exposed due to parting, thinning hair or hairstyles that leave the scalp uncovered.

Who should use Biologique Recherche Lotion P50 Capillaire?

It can be used across Scalp Instants, but we particularly think about it for scalps experiencing excess oil, product buildup, visible flakes, itching or a generally unbalanced feeling.

Where can I buy Biologique Recherche Lotion P50 Capillaire?

Biologique Recherche Lotion P50 Capillaire is available from Loshen & Crem online and at our Edmonton, Alberta boutique.

Our team can also help determine how to incorporate it into your current hair and scalp routine.
