The short answer
Hair is made of keratin, a protein, so low protein intake can lead to thin, brittle hair and shedding. Most adults need about 0.8 g of protein per kilogram of body weight each day, and more with age.
The follicle is one of the fastest-dividing tissues in the body, which makes it sensitive to shortfalls in protein, iron, zinc and B vitamins. It is often among the first places a poor diet shows.
Keratin needs amino acids
Especially sulphur-containing ones found in eggs, fish and legumes.
Mechanical damage from heat, tight styles and rough brushing causes a large share of the breakage people notice. Gentler habits protect the lengths while nutrition supports the roots.
Spread it out
Include a protein source at every meal.
Proven medical treatments exist for pattern hair loss, including topical minoxidil. Supplements support normal growth but are not substitutes for diagnosis and treatment.

Brittle hair, slow nail growth and weak muscles.
A day-one photo of your part and hairline under the same light is the simplest way to judge whether anything is changing over the months that follow.
Vitamins as helpers
B6 and biotin help the body use protein for keratin.
Dermatologists see hair shedding as a symptom rather than a diagnosis. Iron, thyroid function, hormones, stress and medicines are checked first, because the right answer depends on the cause.
A quick checklist
- Photograph your part and hairline on day one.
- Eat protein at every meal.
- Keep heat tools at medium settings.
- Choose loose styles over tight ones.
- Ask your doctor about iron and thyroid tests.
Because scalp hair grows about a centimetre a month, three months of any routine gives you roughly three centimetres of new growth to judge. Patience is not optional with hair.
Putting it into practice
Normal shedding is 50 to 100 hairs a day. Noticing more in the shower after washing is expected; clumps, patches or a widening part deserve a doctor's view.
Take a photo today in natural light, then again in four and eight weeks. Mirrors are poor at showing gradual change, and side-by-side photos often reveal progress you would otherwise miss.

Key takeaway
To sum up: Hair is made of keratin, a protein, so low protein intake can lead to thin, brittle hair and shedding. Nothing here is complicated, and consistency beats intensity.
Before you order, please read this. Gelagen is a dietary supplement, not a treatment for any skin, hair or nail condition. Each serving contains 5,000 mcg of biotin, which the FDA warns can interfere with some lab tests, including thyroid and troponin tests, so tell your doctor before any blood work. Ask first if you are pregnant or nursing, have a thyroid condition or take prescription medicine. Keep gummies out of reach of children, and see a dermatologist about sudden hair loss, new rashes or a changing mole.
