The vitamin complex you add to your shampoo

This is a concentrate - vitamins, minerals and plant extracts in a dropper bottle - that you mix into your shampoo at the moment of washing. The appeal is that it adds nothing to your routine: no extra step, no extra minutes, just a richer version of a wash you were doing anyway.

How to use it

Mix it fresh every time. Do not pour the whole bottle into your shampoo in advance - the concentrate is not formulated to sit in another product for weeks.

• Pour your normal amount of shampoo into your palm.
• Add the number of drops on the label.
• Mix the two briefly with a finger.
• Apply to a wet scalp and massage gently.
• Leave it for one to two minutes before rinsing, so it is not straight down the drain.

What it does, and what it does not

Over time it can contribute to hair that looks stronger and fuller, mostly by improving the condition of the scalp and the hair shaft. It will not regrow hair and it will not reverse genetic hair loss. It is one layer in a routine, and it is honest about being that.

Give it three months

Hair grows about a centimetre a month, so what you do today shows up in the strand weeks later. Three months is the earliest point at which judging it means anything. It works best alongside a decent shampoo as the base and an oral hair vitamin working from the inside.

Who it suits

• People with thinning hair who want to support what they still have.
• Transplant patients in the long-term maintenance phase, once the clinic has cleared normal washing.
• Anyone who has abandoned every routine that needed an extra step.
