Why B-12

Energy for hair, skin & daily life

Vitamin B-12 plays a key role in energy metabolism, nerve function, and healthy blood cells — foundations that support how you feel and how your hair grows.

Boost energy

Helps combat tiredness and low energy linked with B-12 insufficiency — so you can feel more like yourself day to day.

Hair cycle support

Healthy red blood cells deliver oxygen and nutrients toward the scalp — important for follicles and growth cycles.

Efficient delivery

Injection delivers B-12 directly, useful when oral supplements are poorly absorbed or levels need a quicker top-up.

Whole-body wellness

Also supports general vitality and skin radiance when B-12 is part of a broader wellness or hair-care plan.

FAQs

Common questions

Why inject B-12 instead of taking tablets?

Injections deliver B-12 directly into the body, which can be helpful when absorption through the gut is reduced or when you need a more reliable top-up.

How often should I have B-12 injections?

Frequency depends on your levels, diet, and goals. Some clients book monthly; others less often once levels improve. We advise at consultation.

Can B-12 help with hair loss?

B-12 supports energy and healthy blood cells that nourish follicles. It is not a standalone hair-loss treatment but works well as part of a wider hair or wellness plan.

Are there side effects?

B-12 injections are generally well tolerated. Mild soreness at the injection site is possible. Tell us about any medical conditions or medications at your visit.

Do I need a blood test first?

Not always — but recent blood work helps us tailor your plan. We can discuss testing with your GP or as part of your wider care if needed.
