Scalp assessment in content about hair falling out from the root

Discovering clumps of hair in the shower drain or seeing your brush full of strands after combing usually triggers an immediate warning sign. When hair loss occurs very intensely and for a long period—this may represent an excessive increase in the shedding phase (telogen phase), and may be associated with telogen effluvium. 

Unlike breakage, which occurs along the length of the hair, hair loss originates at the root and reveals an imbalance in the physiology of the scalp or in the overall health of the body. Identifying the exact cause is the only way to control the process and stimulate the growth of new, strong, and dense hair.

The Main Triggers of Hair Loss

The hair life cycle is divided into growth, resting, and shedding phases. Under normal conditions, we lose between 50 and 100 strands per day. However, when this count skyrockets, one or more of the following factors are usually involved:

  • Telogen Effluvium (Systemic Stress and Shock): Events of high physical or emotional stress, infections, surgeries, or restrictive diets can cause a large number of hairs to prematurely enter the shedding phase. This type of hair loss usually occurs about 2 to 3 months after the triggering event.
  • Hormonal and Nutritional Changes: Deficiencies in iron, vitamin D, zinc, and protein, coupled with hormonal fluctuations (such as postpartum, thyroid disorders, or menopause), reduce the supply of nutrients delivered to the bulb.
  • Scalp Disorders: Excess oiliness, seborrheic dermatitis, and the accumulation of cosmetic residue create an environment conducive to inflammation of the scalp. This condition contributes to alterations in the natural hair growth cycle.
  • Genetic Predisposition (Androgenetic Alopecia): Triggered by the sensitivity of follicles (in a specific region) to androgen hormones, it causes the progressive miniaturization of the hair strands, making them thinner and thinner until the root (follicle) stops producing (terminal strands), that is, new hairs.

How to Understand the Origin of the Problem

To accurately determine the cause of the hair loss, observation of daily habits should be combined with professional investigation.

  • Analyze the Timeline: Think back to events that have occurred in the last three months. Did you have a high fever, change your diet, experience anxiety spikes, or change your medication?
  • Examine the Scalp: Check for redness, flaking, sensitivity to touch, or excessive oiliness at the roots (scalp).
  • Assess the Thickness of the Hair: If you are experiencing significant hair loss but maintaining the same thickness, it may be a temporary situation. However, if you notice areas with fewer, thinner hairs, this process may be progressive.
  • Consult a Professional: An evaluation by a hair therapist, trichologist, or dermatologist, along with medical blood tests and trichoscopy, is essential to aid in a more accurate diagnosis.

Frequently Asked Questions (FAQ)

In hair loss, the hair strand detaches from the scalp, while breakage occurs along the hair shaft. Intense and persistent hair loss may indicate changes in the hair cycle or scalp health.

What are the most common causes of hair loss from the root?

The main contributing factors include telogen effluvium, hormonal and nutritional changes, scalp disorders, and genetic predisposition.

What signs on the scalp can help identify the cause of hair loss?

Redness, peeling, sensitivity, and excessive oiliness may indicate changes that warrant attention during the investigation of hair loss.
