How to understand your hair type

Describe curl pattern, individual strand thickness and overall density separately. One label cannot tell you every product your hair needs.

Healthy scalp basics

Start with comfortable cleansing and a manageable routine. Persistent itch, pain or visible inflammation needs more than another cosmetic product.

Postpartum hair shedding

Increased shedding can follow childbirth as hormone levels change. It commonly begins a few months after birth and usually improves with time.

Moisture, protein or bond repair?

Read the guide ↗

How hair grows

Follicles cycle through growth, transition and rest. Visible length and fullness change gradually, so a few good wash days cannot establish new growth.

Read the guide ↗

Hair porosity explained

Porosity concerns how the fibre interacts with water and its condition. A floating strand in a glass is not a dependable diagnosis.

Read the guide ↗

Dry scalp or dandruff?

Flaking and itch overlap across several conditions. Appearance alone cannot reliably separate a dry scalp from dandruff or inflammation.

Read the guide ↗

How often should you wash your hair?

Wash according to scalp comfort, oil, activity and styling residue. There is no single number of days that suits every head.

Read the guide ↗

Product build-up and clarifying shampoo

Consider clarifying when a normal wash leaves an unwanted coated feel, but do not use stronger cleansing as the answer to every hair problem.

Read the guide ↗

Growth & Thinning

Hair thinning and shedding explained

Shedding describes hairs being released; thinning describes reduced visible density. Breakage is a strand snapping. These can coexist and need different questions.

Read the guide ↗

Growth & Thinning

Postpartum hair shedding

Increased shedding can follow childbirth as hormone levels change. It commonly begins a few months after birth and usually improves with time.

Read the guide ↗

Growth & Thinning

Hair growth products: what does the evidence show?

Improved shine, reduced breakage and measured follicular regrowth are separate claims. Ask which outcome was actually studied in the product you are buying.

Growth & Thinning

Nutrition for healthy hair

Start with adequate, varied eating. Correcting an identified deficiency is different from taking extra nutrients in the hope of faster growth.

Read the guide ↗

Growth & Thinning

Stress and hair shedding

Stress can be one trigger of delayed diffuse shedding, but it is not a diagnosis to assume when hair changes.

Read the guide ↗

Growth & Thinning

Menopause and changing hair

Hair can change around menopause, but thinning, roughness and scalp discomfort are different concerns. Do not assume one treatment will address them all.

Read the guide ↗

Growth & Thinning

Hereditary hair loss explained

Pattern hair loss can run in families, but family history does not diagnose every instance of shedding or a changing hairline.

Read the guide ↗

Growth & Thinning

When to seek help for hair loss

Book a GP appointment if hair loss worries you. Sudden changes, patches or scalp symptoms deserve assessment rather than repeated product experiments.

Damage & Repair

Moisture, protein or bond repair?

Choose by the problem you can describe: manageability, surface feel or chemical damage. Product categories overlap and none guarantees a permanent reset.

Damage & Repair

How to protect hair from heat damage

Reduce avoidable heat exposure, handle hair carefully and follow tool and protectant instructions. A spray does not make unlimited heat harmless.

Read the guide ↗

Damage & Repair

How to care for bleached and coloured hair

Prioritise careful handling and a conditioning routine you can repeat. Consider further processing decisions as part of care, not just aftercare products.

Read the guide ↗

Damage & Repair

Conditioner, mask or leave-in?

Use a rinse-out conditioner as a starting comparison, then add a mask or leave-in only when it has a clear job.

Read the guide ↗

Damage & Repair

Split ends explained

A product may temporarily smooth the appearance of ends; trimming removes the split portion. Prevention focuses on reducing further wear.

Read the guide ↗

Damage & Repair

How to detangle without unnecessary breakage

Work in manageable sections and release knots gradually rather than dragging a tool through resistance. Adapt the timing to your texture.

Read the guide ↗

Damage & Repair

Protecting hair overnight

Choose a comfortable loose arrangement that limits pulling and tangling. A pillowcase or bonnet is an optional accessory, not a growth treatment.

Read the guide ↗

Routines & Styling

A routine for fine hair

Start with light, targeted conditioning and add styling products sparingly. Fine strands do not automatically mean low density.

Read the guide ↗

Routines & Styling

A routine for dry or coarse hair

Separate rough-feeling lengths from strand thickness. Start with manageable cleansing and conditioning, then adjust amounts to your actual result.

Read the guide ↗

Routines & Styling

A routine for wavy hair

Choose cleansing, conditioning and optional hold around the shape you want. A wavy routine need not contain every product used for tight curls.

Read the guide ↗

Routines & Styling

A routine for curly and coily hair

Build around scalp cleansing, workable detangling and a low-tension style. Curl pattern alone does not determine your washing interval or ideal product weight.

Read the guide ↗

Routines & Styling

How to make hair look shinier

Focus on the surface finish and styling result you want. Shine is an appearance goal, not a reliable measure of follicle health.

Read the guide ↗

Routines & Styling

How to manage frizz

Start by deciding what you want to change: flyaways, rough ends or loss of definition. Frizz is not automatically a sign of unhealthy hair.

Routines & Styling

How to add volume to fine hair

Make root lift and hold a specific styling goal. More volume in a finished style is different from growing more hair.

Ingredients Explained

Silicones explained

Silicones are used in hair care for conditioning and surface effects. Whether you like a product depends on the whole formulation and your routine.

Read the guide ↗

Ingredients Explained

Sulphates explained

Sulphates are one family of cleansing ingredients. Choose a finished shampoo by suitability and comfort rather than treating one ingredient family as a universal verdict.

Ingredients Explained

Protein in hair products

Protein-containing treatments are cosmetic formulations. Their inclusion does not demonstrate a permanent rebuild or that everyone needs a separate protein step.

Read the guide ↗

Ingredients Explained

Hair oils explained

Compare oils by the job you want them to do. A finishing oil, pre-wash oil and essential oil are not interchangeable products.

Ingredients Explained

Rosemary oil and hair growth

There is some human research, but it does not establish that any rosemary oil blend will reliably reverse hair loss.

Ingredients Explained

Caffeine and peptide hair serums

Assess each ingredient and each finished formula separately. A promising mechanism does not establish that a serum produces meaningful regrowth.

Biotin and hair supplements

Supplements are not a default treatment for thinning. Biotin deficiency and extra biotin in someone without deficiency are different questions.

Read the guide ↗

Damage & Repair

Less breakage starts with gentler habits

Focus on where strands are being pulled, rubbed, processed or heated. A careful routine can be more useful than adding another repair claim.
