Shampoo

Shampoo is the foundation of any effective hair-care routine, working to cleanse the scalp, remove excess oil, product build-up and daily pollution while preparing hair for conditioning and styling. This category brings together everyday shampoos, professional salon formulas, scalp-focused treatments and targeted solutions for dry, oily, coloured or thinning hair. Whether you’re looking to buy a gentle daily shampoo, an anti-dandruff formula or a sulphate-free option online, this collection is designed to help you match the right shampoo to your hair type, scalp condition and styling habits.

What Is Shampoo & How Does It Work?

Shampoo is a hair-cleansing product that combines surfactants (cleansing agents) with conditioning and supporting ingredients to lift away oil, dirt, sweat and styling residue from the scalp and hair fibres. When mixed with water and massaged into the scalp, these cleansing agents surround and remove impurities so they can be rinsed away, leaving the scalp feeling refreshed and hair looking clean, lighter and more manageable.

Modern shampoos often go beyond cleansing alone. Many are formulated with targeted ingredients for colour protection, volume, curl definition, scalp soothing or breakage reduction, allowing you to treat multiple hair concerns in a single step. People often pair their chosen shampoo with products from the Hair Conditioner, Hair Styling Products, Hair Care and Hair, Skin & Nails Vitamins collections for a complete routine.

Benefits & Features of the Shampoo Collection

Why Is Shampoo Important for Hair & Scalp Health?

The scalp is living skin that produces natural oils and sheds dead cells. Without regular cleansing, oil, sweat, environmental particles and styling products can accumulate, leading to dull hair, clogged follicles and potential irritation. A well-chosen shampoo helps:

• Maintain a balanced scalp environment for healthier hair growth.
• Reduce itchiness, flaking and oiliness when used consistently.
• Boost the effectiveness of conditioners, masks and serums by removing barriers to absorption.
• Improve the longevity of hair colour and chemical treatments with protective formulas.
• Support a professional, polished appearance by keeping hair fresh and neat day to day.

For people with specific concerns like dandruff or psoriasis, shampoos from our Dandruff, Dry Scalp, Medicated Shampoo and Thinning Hair collections may form a key part of their ongoing care plan.

How to Use Shampoo for Best Results

• Pre-rinse thoroughly: Wet hair completely with lukewarm water; this helps distribute shampoo evenly and reduces friction.
• Focus on the scalp: Apply shampoo mainly to the scalp and roots, where oil and build-up are most concentrated.
• Massage gently: Use fingertips (not nails) to massage the scalp for 1–2 minutes to stimulate circulation and lift residue.
• Don’t overload product: Start with a small amount and add more if truly needed; too much shampoo can be difficult to rinse out.
• Rinse thoroughly: Rinse until the water runs clear to avoid residue that can weigh hair down.
• Condition mid-lengths & ends: Follow with a suitable conditioner or mask from the Hair Conditioner or Hair Repair Treatments collections.
• Adjust frequency: Those with oily scalps may wash daily or every other day; drier or textured hair types may prefer less frequent washing.

Expert Insights on Shampoo & Scalp Science

Hair washers often focus on the strands, but experts emphasise that shampoo is primarily a scalp product. Regular but appropriate cleansing helps manage sebum levels, removes pollution and reduces the risk of follicle-clogging residue. Over-cleansing with harsh formulas, however, can disrupt the scalp barrier, trigger compensatory oiliness and increase sensitivity.

Many trichologists also highlight the link between overall wellbeing and hair quality. Nutritional status, stress, hormonal changes and sleep all influence hair density and shine. That’s why some customers combine their shampoo routine with products from Hair, Skin & Nails Vitamins, Anti-Ageing & Longevity Supplements and Immunity Supplements to support hair from within as well as on the surface.

Targeted regimes may also include specialist brands from Welzo’s wider hair ranges, such as Head & Shoulders,
