Caída del cabello: causas, síntomas y cómo mejorarla de forma natural

The hair loss It is concerning when more hair than usual appears in the shower, on the brush, or on the pillow. Even so, losing between 80 and 100 hairs a day is normal: it's part of the hair's natural cycle. The caída del cabello it becomes a problem when it increases, hair loses density, or new hair grows thinner and thinner.

Hormones, stress, diet, iron levels, weight changes, or thyroid imbalances can alter the hair growth cycle and cause hair loss caída del cabello.

In this guide, you will see the hair loss causes, how to tell the difference between telogen effluvium and androgenetic alopecia, and which habits and supplements can help you care for your hair.

Why does hair loss occur?

Each hair goes through phases of growth, transition, and decline. Under normal conditions, while some hairs fall out, others begin to grow, and that is why a certain hair loss daily is physiological.

However, certain situations cause many follicles to enter the telogen phase, the resting phase prior to hair loss. This can occur after a period of significant stress, during the postpartum period, following rapid weight loss, or due to a nutritional deficiency, and in all these cases, the hair loss increases.

Not all falls are created equal hair loss it is the first step in deciding what to do.

Main Causes of Hair Loss

Hormonal changes and androgenetic alopecia

In the androgenetic alopecia dihydrotestosterone (DHT), which is formed when the 5-alpha-reductase enzyme converts testosterone. It is one of the most common hormonal causes of hair loss

miniaturization: a progressive process in which hair grows increasingly fine, short, and weak.

In women, this hormonal hair loss can appear alongside acne, excess sebum, increased hair growth, or menstrual cycle irregularities. These signs indicate a possible hyperandrogenism (excessive action of male hormones), common in polycystic ovary syndrome. In these cases, FemmeBalance, con Saw Palmetto and Vitex, can accompany a global approach.

Stress, Postpartum, and Telogen Effluvium

Another common cause of hair loss is the telogen effluvium, una pérdida generalmente difusa que aparece semanas o meses después de un desencadenante. Puede ocurrir tras:

• One period of intense stress

• El posparto.

• One disease.

• One rapid weight loss or a very restrictive diet.

• A period of high physical or emotional demand.

postpartum postpartum hair loss is striking, but it does not mean that the follicle has been lost.

Iron, Zinc, and Diet

The hair follicle needs energy, protein, and micronutrients to maintain its activity. Iron is one of the key nutrients to check during a hair loss,

You don't need to have anemia so that your reservations deserve attention. That is why a healthcare professional can evaluate the ferritin (the protein that stores iron) and other markers of iron metabolism. If the lab work shows low reserves, an iron supplement such as FerroPlus

El zinc plays a role in keratin formation, cell division, and tissue repair. In addition, its absorption varies depending on the chemical form in which it is taken, as shown by a comparative study of zinc picolinate, citrate, and gluconate (Barrie et al., 1987). Its role in various female reproductive system disorders has also been described (Nasiadek et al., 2020).

The idea is not to take iron or zinc “just in case,” but to first check with a blood test if there is a real need.

Rapid weight loss

When you significantly reduce your energy or protein intake, the body prioritizes vital functions. Hair growth is not one of them, so highly restrictive diets can cause hair loss due to telogen effluvium. 

It can also occur with treatments that significantly reduce appetite, such as GLP-1 receptor agonists (medications such as semaglutide). A pilot study with semaglutide in people with type 2 diabetes observed changes in intestinal iron absorption (Melis et al., 2025).

For this reason, in these cases it is best not to attribute the hair loss directly to the medication. It is more useful to ensure that you are meeting your needs for protein, iron, zinc, and other nutrients.

How to know what type of hair loss you have?

The way your hair changes provides clues about the origin of the hair loss. Esta tabla resume las diferencias entre las dos causas más frecuentes: 

It is also worth distinguishing the fall from the root cause of hair breakage. Frequent direct heat, bleaching, and certain chemical treatments weaken the fiber without there being an issue in the follicle.

	Efluvio telógeno	Androgenetic alopecia
Drop pattern	Diffused and uniform across the entire head	Wider center part and lower density in the top area
Trigger	Stress, postpartum, illness, weight loss, nutritional deficiencies	Hormonal sensitivity of the follicle and genetic predisposition
Evolution	It usually reverses once the cause is resolved	Progressive if left unaddressed
Cuándo consultar	If it lasts more than a few months or increases	When you notice that new hairs are becoming increasingly fine

¿Cuándo conviene consultar por la caída del cabello?

Not all hair loss should be a cause for concern, but in certain cases, it is recommended to see a professional. Seek an evaluation if completely unpopulated areas, dolor, picor intenso, inflamación o descamación del cuero cabelludo.

Also if the caída del cabello es muy brusca, continues to increase for months, or is accompanied by menstrual irregularities, signs of hyperandrogenism, or changes consistent with a thyroid disorder.

How to Care for Hair Health Through Your Habits

Ensures sufficient protein intake

Hair is mainly composed of keratin Eggs, fish, meat, dairy, legumes, tofu and other protein sources help you meet your daily needs.

You don't need to calculate every meal in grams. It is enough that protein does not take a back seat, especially if you are following a weight loss diet. For example, Include a protein source in every main meal: huevos en el desayuno, legumbres o pescado en la comida y tofu o lácteos en la cena.

Avoid losing weight too fast

If you want to reduce body fat, doing so in a progressive form allows you to better maintain your nutrient intake. A caída del cabello several months after a period of intense restriction usually indicates that the deficit was too aggressive.

If you're already in that situation, restore a sufficient and varied diet is the first step. Afterwards, your hair needs weeks or months to normalize its cycle.

Manage stress and take care of your scalp

Sleeping poorly for a few days does not cause hair loss. However, a intense and prolonged stress can indeed play a role in telogen effluvium, so rest, physical activity, and stress management tools matter as well.

Washing your hair does not cause it to fall out more. The hair you see in the shower was already ready to shed, and not washing it as often as your scalp needs can be counterproductive. You can wash it daily if needed, using the right products for your skin type.

What role can supplementation play?

Supplementation is helpful when a specific need exists, but it is no substitute for identifying the root cause of hair loss.

• Hormonal component. If there is acne, excess sebum, or cycle irregularities, FemmeBalance can complement a comprehensive approach. Its formula includes Saw Palmetto, Vitex, NAC, turmeric, and vitamin B5.

• Zinc. If your intake is insufficient or your needs are increased, Zinc Plus complements the intake of this mineral, which is important for the formation of keratin and other cellular processes of the skin, hair, and nails.

• Iron. If your lab tests show low reserves, especially with heavy periods, FerroPlus provides bisglycinate iron along with vitamin C and other micronutrients involved in its metabolism.

• Antioxidant protection. Anti-OX Global Serves as support against oxidative stress as part of a comprehensive strategy. It is not a specific hair loss treatment.

More supplements don't mean better results. What matters is using only what makes sense for your situation.

Preguntas frecuentes sobre la caída del cabello

Does creatine cause hair loss?

Based on current evidence, we cannot claim that creatine causes hair loss. The concern stems from a 2009 study by van der Merwe et al., published in the Clinical Journal of Sport Medicine. En él aumentaron los niveles de DHT, pero no se evaluó la caída del cabello.

Later, a 2025 randomized clinical trial by Lak et al., published in the Journal of the International Society of Sports Nutrition, directly studied hair density and thickness over 12 weeks. No significant differences were found between creatine and placebo. You can learn more about this topic in our article on creatine and hair loss.

¿Necesito tomar biotina?

Not necessarily. Biotin deficiencies are rare, y tomar dosis elevadas sin indicación no hace que el cabello crezca más.

In addition, the high doses may interfere with certain laboratory tests, including some thyroid and hormone function tests. If you are going to have a blood test, always let them know that you are taking biotin. You can find more information in our article on biotin for hair.

How long does it take for hair loss to improve?

The hair cycle needs time. The hair that falls out today began entering the telogen phase weeks or even months ago, so changes in hair loss are not evaluated in a few days.

After correcting the cause, it is usually wait several months to feel it less hair loss and denser hair. If the loss continues after that time, consult a professional.

What to do if your hair is falling out

When hair falls out more than usual, it's tempting to look for a quick fix. But you don't always need another shampoo, biotin, or five supplements at once. 

If you notice that your hair loss identify what has changed in recent months: diet, stress, hormones, weight, or iron reserves. A blood test and a professional assessment will help you decide if you need nutritional support. If this sounds like your situation, discover FerroPlus
