Watermans Hair Growth Shampoo & Conditioner — Biotin & Argan Oil duo for thinning hair and scalp support

Watermans Grow Me® Hair Growth Shampoo & Conditioner is a caffeine-enhanced hair-care duo formulated with biotin, argan oil, niacinamide, rosemary, lupin and allantoin to support thicker-looking hair and a healthier scalp for both men and women.

Designed and made in the UK by Watermans, this pair combines targeted active ingredients and salon-grade conditioning agents to address hair that is fine, brittle, or showing signs of advanced thinning. Rather than promising miracles, the formula aims to strengthen strands, improve scalp condition, and create an environment that supports the natural hair growth cycle. It’s fragrance-balanced, suitable for routine use, and created for people who want to improve hair density, manage breakage, or revitalise ageing hair.

How does this shampoo and conditioner encourage thicker-looking hair?

The formulation uses caffeine and niacinamide to help stimulate scalp circulation and biotin plus lupin proteins to support keratin structure in the hair fibre. Conditioning agents including argan oil and allantoin smooth the cuticle, which makes each strand appear fuller and more resilient.

• Caffeine to support scalp microcirculation
• Biotin and lupin proteins to strengthen hair structure
• Argan oil for moisture and reduced breakage
• Allantoin to soothe and condition the scalp

Can it be used on coloured or chemically treated hair?

Yes — the gently formulated shampoo and the nourishing conditioner are safe for dyed and chemically treated hair when used as directed. The blend helps restore bounce and shine to colour-treated hair while avoiding harsh sulfates that strip colour.

• Colour-safe cleansing agents
• Conditioners that lock in moisture and reduce fading
• No aggressive surfactants that damage processed hair
• Suitable for regular use in colour-care routines

How should I use the duo for best results?

Use the shampoo to cleanse and activate the scalp, massaging gently for at least 60 seconds to optimise ingredient uptake. Follow with the conditioner, leaving it on for 2–5 minutes on mid-lengths to ends to restore moisture and reduce breakage.

• Apply shampoo to wet hair, lather, and rinse thoroughly
• Massage conditioner through lengths, avoiding heavy scalp buildup
• Use regularly — daily or several times weekly depending on your scalp type
• Pair with a gentle brush and avoid heat overuse for best outcomes

What kind of scalp and hair concerns does Watermans target?

Watermans focuses on improving the health of both scalp and hair fibre to reduce breakage-related fall, revive hair affected by age or hormonal changes, and restore texture in lifeless or thinning hair. The ingredients are chosen to balance nourishment, stimulation and conditioning rather than to mask problems.

• Advanced thinning and reduced hair volume
• Breakage-prone, brittle, or fragile strands
• Age-related thinning and menopausal hair changes
• Dull or chemically-treated hair needing resilience

Who is this for? Watermans Grow Me® Shampoo & Conditioner is aimed at adults of all genders experiencing fine or thinning hair, hair weakened by chemical treatments, or anyone seeking a stronger, more resilient head of hair.
