Why is my hair always lacking nutrients?

Aug 14, 2026Safia A.

Do you feel like your curly hair lacks vitality, is thinning or struggles to grow despite all your efforts, a balanced diet and a well-established hair routine? It’s a very common frustration when caring for textured hair.


If your external care no longer seems to work, your hair may be facing nutritional deficiencies. But don't worry: it's not down to your efforts or your routine. The answer lies directly in your body's biology.


In this article, find out why your diet, even the healthiest one, isn't always enough to provide the nutrients essential for healthy hair, and how to get back strong, dense hair full of vitality.

Understand the source of the problem

Your hair: the last to be served from your plate

When it comes to the vitamins, minerals and trace elements we ingest, our body makes strict choices: it always prioritizes the vital organs (heart, brain, lungs). Since hair is not considered essential to our survival, it is systematically the last to benefit from our diet.


As a result, your hair, just like your nails, is the last to be served by the body. Nutrients essential to healthy hair, such as zinc, iron, magnesium and B vitamins, often struggle to reach the hair bulb in sufficient quantities.


What's more, the body can find it hard to absorb certain nutrients. Iron, for example, cannot be properly absorbed without the presence of vitamin C. In other words, even when your diet is rich in essential nutrients, their effectiveness often depends on their combination with other key elements.


Naturally drier and more fragile, wavy, curly, coily and afro-textured hair is often the first to reflect these deficiencies: loss of density, slower growth, breakage or less defined curls.

Signs of a hair deficiency you shouldn't ignore

How can you tell if your hair needs a boost from within? Several signs should alert you: more hair loss than usual, hair that is getting finer and losing density, slower growth, recurring breakage along the lengths, or curls losing bounce and definition despite regular hydration.


When these signs persist even though your external routine is well established, it's often a sign that the problem comes from within, not from the bottle.

Fill deficiencies from within

When diet alone isn't always enough to cover all the needs essential to healthy hair, it can make sense to provide targeted support from within. 


The goal is not to pile on treatments or complex formulas, but to give the body the essential nutrients it may be lacking, in order to promote healthier, stronger and more resilient hair over time.

The JIA Paris solution: Gummies Hair Vitamins

With this in mind, we created JIA Paris Gummies Hair Vitamins, an expert solution to support hair growth, limit hair loss and restore volume to curly and textured hair.

A true concentrate of benefits, its 100% vegan, no-added-sugar formula combines Zinc, Biotin, Iodine, Choline and a powerful complex of vitamins (A, B, C, D and E) to fill your deficiencies from within.

Dietary supplements designed for long-lasting hair health

At JIA Paris, we are convinced that a healthy, concentrated and natural composition is enough to support the beauty and health of hair over the long term.


That is why our food supplements have been formulated to precisely meet the essential needs that hair may lack day to day.

A complete, targeted formula

Our Gummies Hair Vitamins combine actives known for their effectiveness:


  • Zinc
  • Biotin
  • Iodine
  • Choline
  • Vitamins A, B, C, D and E

This blend of ingredients helps support hair growth, make up for certain deficiencies and promote better absorption of essential nutrients.

A clean, committed formula

100% clean and vegan, our gummies stand out from conventional food supplements:


  • No added sugar
  • Gluten-free
  • A respectful and transparent formula

A simple, effective routine

No need to pile on products or doses. 


Just one delicious raspberry-flavoured gummy a day is enough to nourish your hair from within and effectively complement your hair routine.

The 3-month course of Gummies Hair Vitamins

To meet this biological need over the long term, JIA Paris offers three-month dietary supplement courses.


Designed to fit easily into your daily life, just one dose a day is enough to nourish your hair from within and effectively complement the action of your hair care products, for optimal results.

A response tailored to your hair's biology

Making up for hair nutritional deficiencies takes patience.


To stop hair loss, stimulate growth and restore volume to your curls, it is essential to respect the natural hair renewal cycle.


Following a three-month course continuously supplies the hair bulb with essential nutrients such as biotin, zinc, iodine and vitamins A, B, C, D and E. By supporting the hair's natural cycle over time, it works in depth and fully reveals the potential of the active ingredients.

Lasting results

A one-month course helps kick-start a routine and give hair initial support.


But to get visible and, above all, lasting results, a three-month course is the ideal duration.


While the first effects can be felt from the first month, the full three-month course is essential to lastingly build the strength and density of the fiber.

Is a balanced diet enough for healthy hair?

Not always. The body prioritizes vital organs: hair is served last. Even with a healthy diet, some nutrients (zinc, iron, B vitamins) don’t always reach the bulb in sufficient quantities, hence the value of a targeted course.

Which vitamins stimulate curly hair growth?

The most useful are biotin (vitamin B8), zinc, iron, vitamin C (which promotes iron absorption) and vitamins A, D and E. JIA Paris Gummies Hair Vitamins bring these actives together in a single daily dose.

How long does it take to see results with a course of hair gummies?

Hair grows slowly: you need to follow the course for at least 3 months, ideally repeated 2 to 3 times a year, to see lasting effects on density and strength.

Are JIA Paris hair gummies suitable for all hair types?

Yes. They are formulated for all hair types and are particularly suited to textured hair, which is more fragile. They are vegan, sugar-free and gluten-free. Suitable from age 12; if you have a thyroid disorder or are undergoing medical treatment, ask a healthcare professional for advice.
