Does calcium deficiency cause hair loss?

A lack of calcium might be the reason for your hair loss. Calcium is an important mineral that keeps our body in good shape and if there is a shortage of it, our hair may bear the consequences.

Calcium deficiency can undoubtedly cause hair loss. The main point is that calcium is a source of energy for the hair follicles so if it is not enough in the body, the hairs will be thinned and will fall out. Besides that, calcium also plays a role in the production of keratin (the protein that hair is made of) so without enough calcium, the hair will be weak and breaking off easily.

Still, hair loss is incompletely associated with calcium deficiency and it is advisable always to check with a blood test before taking calcium pills.

In addition to that, it is quite a complex matter whether the reason behind losing hair is calcium deficiency only or the other causes, so a consultation with a doctor or a trichologist is the best way to get a diagnosis and a treatment plan.

In brief, lack of calcium might be the reason for losing hair and it is very important to keep a well-balanced and varied diet in order to meet not only calcium but other mineral needs as well. Besides that, if you feel that you are low in calcium or have other symptoms along with hair loss, make an appointment with a doctor without delay.

Signs Your Hair Loss May Be Nutrient‑Related

What You Can Do About It

• Get blood tests for calcium, vitamin D, ferritin (iron), and thyroid before self‑supplementing.
• Include calcium‑rich foods like dairy, ragi, sesame, leafy greens, and fortified products, along with vitamin D from sun or supplements as advised.
• Address lifestyle triggers: crash diets, high stress, and restrictive eating can worsen both deficiency and hair loss.

Conclusion

If you are losing hair, think of “overall health” rather than just “one mineral.” Calcium deficiency can play a role, but fixing the full nutrient picture and underlying conditions gives the best chance for thicker, healthier hair.
