ABOUT THIS COLLECTION

Give your hair and scalp targeted care with our Hair Serum collection at Coal Harbour Pharmacy. Hair serums are concentrated leave-in treatments designed to address specific concerns at either the scalp and roots or along the hair shaft and ends.

Our pharmacist-curated collection includes hair growth and density serums, scalp treatments, anti-frizz serums, strengthening formulas, shine-enhancing treatments, and protective leave-in products from trusted professional and personal-care brands.

Depending on their purpose, formulas may contain ingredients such as caffeine, peptides, botanical extracts, amino acids, panthenol, argan oil, jojoba oil, antioxidants, and conditioning agents. Scalp-focused serums help maintain an optimal environment for healthy-looking hair, while cosmetic hair serums smooth the cuticle, reduce friction, control frizz, and improve shine and manageability.

Whether you’re concerned about thinning, breakage, dryness, frizz, or scalp condition, the right serum can add a targeted treatment step without weighing down your routine.

WHAT HAIR SERUMS DO

Not all hair serums work in the same way.

Scalp serums are applied directly to the scalp and may contain ingredients intended to condition the scalp or support the appearance of fuller, healthier hair.

Hair-shaft serums coat or condition the surface of the hair to reduce friction, improve smoothness, control frizz, and enhance shine.

Repair-focused serums can help temporarily reinforce and condition damaged areas, reducing the appearance and feel of dryness or breakage.

Understanding the intended application area is important when choosing a serum.

TYPES OF HAIR SERUMS

Hair Growth & Density Serums

These leave-in scalp treatments are formulated to support the appearance of fuller, denser, healthier-looking hair.

Depending on the product, ingredients may include:

• Caffeine

• Peptides

• Amino acids

• Botanical extracts

• Niacinamide

• Panthenol

• Antioxidants

• Other scalp-supporting actives

Results vary substantially between formulas, and cosmetic hair-growth serums should not automatically be considered equivalent to clinically established hair-loss treatments.

Scalp Treatment Serums

Scalp serums provide targeted care without necessarily coating the entire hair shaft.

They may help support:

• Scalp hydration

• Dryness and tightness

• Oil balance

• Scalp comfort

• Healthy-looking scalp condition

• An optimal environment for normal hair growth

Choose products specifically designed for scalp application and follow their individual directions.

Anti-Frizz & Smoothing Serums

These formulas coat the hair surface to improve smoothness and manageability.

They can help:

• Control flyaways

• Reduce frizz

• Improve detangling

• Smooth rough-looking ends

• Enhance softness

• Add shine

They are particularly useful for dry, coarse, curly, textured, or humidity-prone hair.

Shine Serums

Shine-enhancing serums help create a smoother surface that reflects light more evenly.

Common ingredients may include:

• Argan oil

• Jojoba oil

• Lightweight plant oils

• Conditioning agents

• Silicones or silicone alternatives

• Antioxidant oils and extracts

Use sparingly, particularly on fine hair.

Repair & Strengthening Serums

Hair damaged by colouring, bleaching, heat, or mechanical stress can become more porous and susceptible to breakage.

Strengthening formulas may contain:

• Hydrolyzed proteins

• Amino acids

• Keratin-derived ingredients

• Ceramides

• Peptides

• Conditioning polymers

• Plant oils

These products can improve the feel and appearance of damaged hair and help reduce further breakage, but they cannot permanently reconstruct severely damaged hair fibres.

Heat & Environmental Protection Serums

Protective leave-in treatments can help reduce damage associated with blow-drying, flat irons, curling tools, UV exposure, humidity, and other environmental stressors.

Choose a product specifically labelled for heat protection when using heated styling tools.

KEY INGREDIENTS TO LOOK FOR

Caffeine

Caffeine is used in some topical scalp formulas and has been investigated for its potential effects on hair follicles.

Evidence varies by formulation, so caffeine-containing cosmetic serums should be viewed as supportive rather than guaranteed hair-regrowth treatments.

Peptides

Peptides are incorporated into some scalp and hair-density formulas to support conditioning and the appearance of healthier hair.

Their effectiveness depends on the specific peptide, concentration, and formulation.

Biotin

Biotin is frequently marketed for hair health, but topical biotin should not automatically be expected to stimulate hair growth.

Biotin deficiency can affect hair health, while evidence for topical biotin as a stand-alone hair-growth treatment remains limited.

Argan Oil

Argan oil is rich in lipids that help condition dry hair, improve softness, reduce friction, and enhance shine.

Jojoba Oil

Jojoba oil is commonly used in scalp and hair products for lightweight conditioning and moisture support.

Panthenol

Panthenol, or provitamin B5, is a humectant and conditioning ingredient that can help improve moisture, softness, and hair feel.

Niacinamide

Niacinamide may be incorporated into scalp formulations for its skin-conditioning and barrier-supporting properties.

HAIR SERUMS FOR THINNING & SHEDDING

Hair thinning and excessive shedding can have many causes, including:

• Hereditary hair loss

• Hormonal changes

• Postpartum changes

• Stress or illness

• Nutritional deficiencies

• Thyroid disorders

• Certain medications

• Rapid weight loss

• Scalp conditions

• Aging

A cosmetic serum may improve scalp condition or the appearance of hair density, but persistent hair loss should be evaluated to identify the underlying cause.

Evidence-based treatments may be available for certain types of hair loss, and a pharmacist, physician, or dermatologist can help determine which approach is appropriate.

HOW TO CHOOSE THE RIGHT HAIR SERUM

• For thinning hair: Choose a scalp-focused density or hair-support serum

• For scalp dryness: Select a hydrating scalp treatment

• For frizz: Choose a smoothing or anti-frizz serum

• For damaged hair: Look for strengthening and conditioning formulas

• For dry ends: Choose an oil-based or moisture-supporting serum

• For shine: Select a lightweight finishing serum

• For fine hair: Use lightweight formulas sparingly

• For curly or textured hair: Consider richer smoothing and moisture-supporting serums

• For heat styling: Choose a product specifically formulated for thermal protection

• For personalized recommendations: Consult our pharmacy team

HOW TO USE HAIR SERUM

Always follow the directions for the specific product, as application differs between scalp and hair serums.

For scalp and density serums:

• Apply directly to the scalp as directed

• Part the hair to improve scalp access

• Massage gently if recommended

• Leave in unless the label instructs otherwise

• Use consistently according to the recommended schedule

For smoothing and shine serums:

• Start with a small amount

• Apply primarily to mid-lengths and ends

• Use on damp or dry hair depending on the formula

• Avoid excessive application near the roots if your hair is fine or oily

• Do not rinse unless instructed

Using more serum than recommended does not necessarily improve results and may leave hair looking heavy or greasy.

BUILD A COMPLETE HAIR & SCALP ROUTINE

Cleanse: Use a shampoo appropriate for your scalp and hair type.

Condition: Restore moisture and improve manageability with an appropriate conditioner.

Treat: Apply a targeted scalp, density, strengthening, or repair serum.

Protect: Use thermal protection before heat styling when appropriate.

Finish: Apply a lightweight smoothing or shine serum to the lengths and ends if needed.

Support: Maintain adequate nutrition and investigate persistent shedding or thinning rather than relying exclusively on topical cosmetics.

CAUTIONS & CONSIDERATIONS

Hair serums are generally intended for external use unless otherwise stated.

• Follow individual product directions

• Avoid eye contact

• Discontinue use if significant irritation develops

• Patch testing may be useful for highly sensitive skin

• Essential oils and botanical extracts can cause irritation or allergic reactions in some individuals

• Do not apply products to broken or significantly inflamed skin unless specifically directed

Seek professional assessment for:

• Sudden hair loss

• Patchy bald areas

• Rapidly progressing thinning

• Significant scalp pain or inflammation

• Scarring or sores

• Persistent unexplained shedding

• Hair loss accompanied by other unexplained symptoms

FAQ

What does hair serum do?
It depends on the formula. Scalp serums target scalp condition or the appearance of hair density, while cosmetic serums primarily smooth, condition, reduce frizz, protect, and add shine to the hair shaft.

Can hair serum make hair grow?
Some scalp serums contain ingredients studied for hair and follicle support, but results vary and many cosmetic serums do not have strong evidence for actual hair regrowth. Persistent hair loss should be properly assessed.

Can I use hair serum every day?
Many serums are formulated for daily use, but frequency depends on the product and your hair and scalp type. Follow the manufacturer’s directions.

Should hair serum be applied to wet or dry hair?
Both are possible. Smoothing serums are commonly used on damp or dry lengths, while scalp treatments may have specific application instructions.

Should I put hair serum on my scalp?
Only if the product is specifically designed as a scalp serum. Traditional smoothing and shine serums are generally intended for the mid-lengths and ends.

Can hair serum reduce breakage?
Conditioning and strengthening serums can reduce friction and improve flexibility and manageability, which may help limit mechanical breakage.

Is hair serum suitable for colour-treated hair?
Many are, but check the individual product label. Colour-treated hair may particularly benefit from moisturizing, smoothing, and protective leave-in products.

How long does a hair-growth serum take to work?
Hair grows slowly, so products targeting density generally require consistent use over an extended period. Timing and results depend on the formulation and the underlying reason for thinning.
