Three Months After Giving Birth, My Hair Comes Out by the Handful Every Time I Wash It
If hair falls out all at once two to three months after childbirth, rapid weight loss, or a high fever, telogen effluvium is a likely cause. Telogen effluvium that appears after childbirth is commonly called postpartum hair loss. Patients often come in startled after finding hair piled up in the shower drain and on the pillow around 100 days after giving birth, or afraid to wash their hair after losing several kilograms in a single month.
Childbirth and abrupt dietary restriction place major stress on the body and are typical triggers that disrupt the rhythm of hair growth.(Chien Yin GO et al., 2021) Fortunately, in acute telogen effluvium, once the trigger has passed, the amount of shedding usually decreases naturally within about six months and the hair recovers. Even after the number of shed hairs returns to a normal range, however, it takes longer for the short new hairs to grow as long as the existing hair and for overall fullness to return.(Asghar F et al., 2020)
Why Does Hair Loss Start Only Two to Three Months Later?
Scalp hair cycles through three phases in sequence: an active growth phase (anagen), a phase in which growth stops (catagen), and a resting phase in which activity stops completely (telogen). Under normal conditions, most hairs stay in the growth phase, and only around 50 to 100 resting-phase hairs shed naturally each day. However, when the body goes through a sharp hormonal shift after childbirth, weight loss with extremely restricted nutritional intake, or a severe fever of 38°C or higher, a large number of hairs cannot remain in the growth phase and shift abruptly into the resting phase at nearly the same time.
Hair that has moved into the resting phase does not fall out right away. It stays in the follicle for a waiting period, usually about two to three months. That is why there is a time lag, and the hairs fall out together only two to three months after the day the body went through the extreme stress.(Malkud S, 2015) When shedding increases this dramatically, changes in the nerves and microcirculation around the follicles may also bring a tingling or prickling pain to the scalp.(Rebora A, 2019)
How the Shedding Pattern Differs from Alopecia Areata and Crown Hair Loss
Telogen effluvium does not hollow out one particular area; the hair sheds evenly across the whole head, spreading out without scarring. Alopecia areata, by contrast, results from an autoimmune reaction and is easy to tell apart because it leaves clearly bordered, coin-shaped bare spots. In androgenetic alopecia, on the other hand, the hair around the crown and the part gradually becomes finer, so the difference in hair thickness is what stands out first. It often progresses alongside telogen effluvium, so an accurate distinction is necessary.(Rebora A, 2019)
We first examine how the shedding is distributed and how much hair thickness varies. When needed, we perform a wash test, which counts how many hairs are shed while washing over several days, or a trichogram, which analyzes the shape of the hair roots.(Asghar F et al., 2020) We may also photograph the scalp at regular intervals to track changes in hair density and thickness. If coin-shaped bare spots are clearly visible, or if the scalp is red and swollen with oozing or scarring, suspect an inflammatory scalp condition or a scarring alopecia that can leave permanent damage rather than simple telogen effluvium, and get a prompt, thorough examination.
Why Blood Tests Start with Thyroid, Iron, and Vitamin D
We compare the delivery date, the point when weight loss began, and the dates of any high fever against the onset of hair loss, and we carefully review current medications, usual food intake, the degree of bleeding after childbirth, and whether the patient is breastfeeding. When bleeding during delivery was heavy, when breastfeeding has caused significant nutritional depletion, or when a diet excessively restricted protein and calories, essential raw materials do not properly reach the cells that make hair.
Based on this history, we run blood tests to identify endocrine disorders and deficiency states.(Malkud S, 2015) At this stage, we always check thyroid hormone levels, which regulate hair metabolism; ferritin, which reflects the body's stored iron; and vitamin D levels, which are involved in hair follicle formation. Treatment centers on correcting the trigger identified in this way.(Asghar F et al., 2020) If iron or other nutrients are deficient, we adjust the diet and add supplementation; if thyroid disease is diagnosed, treating that underlying condition takes priority. If a drug side effect is suspected, we discuss adjusting the prescription to restore an internal environment in which hair can grow back.
When Shedding Doesn't Decrease After 6 Months
If hair shedding persists for more than 6 months, it is classified as chronic telogen effluvium. At that point, we need to reassess whether an unresolved nutritional deficiency, a chronic illness, or androgenetic alopecia is progressing alongside it.(Asghar F et al., 2020)(Rebora A, 2019) When hair loss has become chronic and the scalp environment has deteriorated, step-by-step management is needed. We systematically improve the hair growth environment through the Head Reset Fit program.
Head Reset Fit begins with a precise scalp diagnosis that closely analyzes the condition of the scalp and hair follicles, muscle tension in the neck and shoulders, and the blood flow and lymphatic circulation leading to the scalp. Based on the diagnostic findings, we use lymph opening to aid circulation and a release to loosen stiff tension in the scalp fascia, and we promote circulation in the deep scalp tissue with WINBACK radiofrequency used together with Lympha-TE sonic waves. We then select active ingredients such as growth factors, stem cells, and exosomes to match each person's scalp condition and inject them precisely into the dermal layer of the scalp with a Dermashine multi-injector. These injections are given to boost the vitality of hair follicle cells. Before the procedure, we fully explain the nature of the formulation, the clinical evidence behind it, and temporary reactions such as redness or bruising. The cycle and combination of the program are adjusted to each person's pace of recovery.

Frequently Asked Questions
Q. Can I keep breastfeeding while I'm losing a lot of hair from postpartum hair loss?
There is no need to stop breastfeeding because of postpartum hair loss alone. While breastfeeding, get enough calories and protein. If you start a hair loss medication, tell your doctor that you are breastfeeding and how old your baby is in months before the type of medication and whether to use it are decided.
Q. If I have telogen effluvium, should I wash my hair less often?
Hair that falls out while washing has usually already entered the shedding stage, so washing less often will not stop the hair loss from progressing. Wash according to your scalp's oil and sweat, and avoid scratching with your nails or pulling hard on wet hair.
Q. If hair loss develops after dieting, should I start by taking iron or biotin?
Rather than starting with supplements, the principle is to adjust the restricted amount of food and nutritional balance and to supplement the nutrients confirmed to be deficient at the dose needed. High-dose biotin can affect the results of some blood tests, so if you are taking it, tell your doctor the product name and dose before the test.
Q. Should minoxidil be used for telogen effluvium too?
Minoxidil is not always necessary in acute telogen effluvium; its use is considered when shedding lasts a long time or when androgenetic alopecia is also present. Shedding can increase temporarily early in use, so record when you started and how it progresses, and if you are pregnant or breastfeeding, check the medication's safety before use.
