The tingling sensation on your scalp can be a sign of inflammation, a symptom that accompanies hair loss. However, it can also be the result of new hair growth. The sensation occurs because many hair follicles are getting active simultaneously.
Typically when your hair begins to grow back, your scalp may be itchier than normal. Think of the hair growing back after shaving your legs. When the hair is popping through the skin, it's not at all uncommon to feel some slight irritation or itchiness.
A tingling feeling in the scalp (paresthesia) can occur for many reasons, including anxiety, ASMR, chemical irritation, medication, migraines, nerve compression, skin sensitivity, and underlying health conditions. See your healthcare provider if you have ongoing scalp tingling.
One of the signs of hair growth is that it grows very close to the scalp, particularly in the early stages of regrowth. Sometimes, the initial growth looks like short, "peek-a-boo" hairs that can be visible when the hair is styled or brushed in a certain way.

Possible causes of tingling in the head include sinus infections, anxiety, headaches, diabetes, and more. Certain medications and a head injury may also cause tingling in the head. Understanding related symptoms can help a person identify the possible cause of tingling in the head.
Formication. Hallucinating the feeling of insects crawling on your skin is known as formication. The sensation occurs because your brain is misinterpreting signals from your body, a type of tactile hallucination — it's related to your sense of touch.
It is common for these sensations to occur in the scalp due to the high number of sensory nerve endings there. Abnormal sensations of tingling, burning, prickling, or a feeling of pins and needles are called paresthesias.
Stylists say the easiest way to do this is by examining the ends. “Breakage often appears frayed or split at the end, while new growth tends to have a smooth, tapered tip,” says Ona Diaz-Santin, the owner of 5 Salon & Spa in Fort Lee, New Jersey.
Short Length: Because it is just beginning to grow from the hair follicle, new hair growth is typically short at first. It may manifest as finer, shorter hairs on the scalp.
There is a common misconception that scratching an itchy scalp promotes hair growth. However, the reality is quite the opposite. Repeated or intense scratching can actually damage the skin and hair follicles due to friction, potentially leading to temporary hair loss instead of growth.
This cycle can be divided into three phases: anagen (growth), catagen (transition), and telogen (rest). Anagen growth is the active phase in which the hair follicle takes on its onion-like shape and works to produce the hair fiber. The anagen phase can be further broken down into proanagen and metanagen phases.
Anagen: The first phase of hair growth takes between two to seven years. Growth begins at the root (dermal papilla) in your hair follicle, which gives your hair blood supply and the nutrients it needs to grow. Your hair grows about 1 centimeter per month.
Soreness — Many individuals report experiencing a sore or tender scalp as new hair starts to grow. “I had soreness when my hair fell out and again when it started to grow back in,” one member explained. This sensation is often likened to the feeling of a mild sunburn or tension in the scalp.
Many factors can cause paresthesia — a tingling, prickling, or pins-and-needles sensation — on the scalp, including anxiety, problems with the nerves, and skin conditions such as psoriasis or eczema. In most cases, tingling on the scalp is temporary.
Formication, or parasitosis, is the sensation of having insects crawling on or under the skin. Formication is a tactile hallucination, which means a person feels a physical sensation without a physical cause. The name formication comes from the Latin word “formica,” which means ant.
Key Vitamin Deficiencies
Vitamin B12: Essential for nerve health, a deficiency can cause nerve damage and result in sensations like formication. Iron: Low iron levels can lead to anaemia, which has been linked to crawling skin sensations.
Deficiency in vitamin B12 can also impact the nerves and cause tingling. Poor posture can cause compression of nerves in the neck and back of the head.
Go to a hospital or call 911 or the local emergency number if: You have weakness or are unable to move, along with numbness or tingling. Numbness or tingling occur just after a head, neck, or back injury. You cannot control the movement of an arm or a leg, or you have lost bladder or bowel control.
Contact your provider any time you notice new symptoms or sudden changes that are abnormal for you, such as a new weird feeling in your head that comes and goes, sudden changes in frequency of déjà vu or other abnormal symptoms.
Short hairs in thinning areas are usually a sign of hair growth. These hairs may start out as small dark spots on your scalp as they begin to grow from the hair follicle and out through your skin.
Telogen Phase. Telogen stage is the final phase of the hair growth cycle, where hair is at rest (resting phase). During this stage, the old hair is shed, making way for new hair growth to begin. On the scalp, approximately 10-15% of hair is in the telogen phase at any given time.
