Hair & immune

Vitamin D injection

Top up vitamin D with a direct injection — supporting immune balance, follicle health, and the skin radiance that often fades when levels run low, especially through darker months.

Why vitamin D

Support from the inside out

Vitamin D influences immune function, mood, bone health, and processes linked with healthy hair follicles and skin — many UK adults run low without realising.

Follicle health

Vitamin D receptors are present in hair follicles — adequate levels support a healthier environment for growth cycles.

Immune balance

Helps modulate immune responses — relevant for scalp health and general wellbeing.

Skin & mood

Often chosen when low sun exposure affects skin quality, energy, and how you feel day to day.

Reliable top-up

Injection offers efficient delivery when oral doses are inconsistent or absorption is a concern.

FAQs

Common questions

Why is vitamin D linked to hair loss?
Low vitamin D is commonly seen in people with hair thinning. While it is not the only cause, correcting deficiency can support follicle health as part of a wider plan.
How often will I need injections?
This depends on your blood level, diet, sun exposure, and how you respond. Some clients need more frequent sessions initially, then maintenance top-ups.
Can I take too much vitamin D?
Yes — vitamin D should be dosed appropriately. We review your history and any existing supplements to keep treatment safe.
Injection vs oral vitamin D?
Injections deliver vitamin D directly and can be useful when levels are low or absorption is unreliable. Your clinician will advise the best approach for you.
Will this help my skin too?
Many clients notice improved overall wellbeing and skin quality when deficiency is addressed — alongside benefits for hair and immune health.
