Hair transplantation is a surgical procedure. Through this method, hair follicles are harvested from a dense (donor) area at the back of the head and implanted into the areas where hair is absent; this process of implantation is known as a hair transplant.










(Follicular Unit Extraction) is one of the most popular and minimally invasive hair transplant techniques. In this method, individual hair follicles are carefully extracted from the back of the scalp (donor area) using micro-punch tools and then implanted into areas affected by hair loss or thinning.
is an advanced hair transplantation technique. In this method, hair follicles are extracted from the back of the head (the donor area) and then implanted directly into the hairless or thinning areas (the recipient area) using a device called the Choi Implanter Pen.
is an advanced version of the traditional FUE technique. In this method, tiny incisions are made in the recipient area using special blades made from sapphire gemstone. These sapphire blades are known for their sharpness and smooth surface, allowing more precise cuts with minimal damage to the skin. In contrast, the conventional FUE technique typically uses steel blades or needles.
is a hair transplant method. In this technique, a strip of skin with healthy hair follicles is taken from the donor area, usually the back of the head. This strip is then divided into small individual grafts under a microscope. After that, these grafts are placed into the bald or thinning areas of the scalp. This method is also known as the “strip method” and is often used when a large number of grafts are needed for hair transplantation.
Hair loss is classified using a scale called the Norwood Scale for men, and the Ludwig Scale for women. Most surgeons refer to the Norwood Scale when estimating graft requirements. The higher the grade, the larger the bald area, and the more grafts needed to restore adequate density.
The table below gives a general estimate. These are not fixed numbers — your final graft count depends on factors like your natural hair density, hair texture (finer hair may need more grafts to achieve the same coverage), the size of your bald area, and how much donor hair is available. This is exactly why a proper scalp evaluation matters before any numbers are discussed.
Norwood Grade | Baldness Pattern | Grafts Needed | Recommended Technique |
Type 1–2 | Slight recession at temples | 1,500 – 2,500 | FUE |
Type 3 | Noticeable recession, early thinning on crown | 2,500 – 3,000 | FUE or FUT |
Type 4 | Clear separation between frontal and crown hair | 2,800 – 3,500 | FUT or FUE+FUT |
Type 5 | Large bald area on top, thin bridge of hair | 3,500 – 4,500 | FUE + FUT Combined |
Type 6–7 | Near-complete baldness on top and crown | 4,500 – 7,000+ | Mega Session FUT + FUE + PRP |
If you are planning a hair transplant in Kolkata, you should know how the cost of a hair transplant in Kolkata is decided. When you come to us, we first check your scalp and see how much hair loss you have, because some patients only need the front hairline, while others need coverage up to the crown, and this decides how many grafts you need and the total cost. We also check your age and health history like diabetes, blood pressure, or thyroid problems to make sure the treatment is safe for you. Your donor area from the back and sides of the head is also checked because a strong donor area gives better results. The method used also changes the cost, where FUE is around ₹25–₹30 per graft and DHI is around ₹40–₹70 per graft because it is more advanced and precise. Clinic care, hygiene, and experience also matter. In simple words, the cost of hair transplant in Kolkata depends on your hair loss, donor area, health condition, and the method we choose for you, and we always plan it in a simple and safe way for natural results.If you’re looking for an affordable hair transplant in Kolkata, it’s always better to choose a clinic that explains the cost clearly and guides you properly, so you know exactly what you’re paying for and what results to expect.

Yes,Hair transplant is permanent.
Most patients can return to normal daily activities within 7-10 days, but full recovery and best results take around 8–12 months.

Losing hair can affect more than just your appearance; it impacts your confidence, self-image, and daily life. Whether you’re dealing with male or female pattern baldness, a receding hairline, patchy beard, or thinning eyebrows, a hair transplant offers a medically proven, permanent solution. Using advanced techniques like FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplant), your own healthy hair follicles are relocated to thinning areas growing naturally, needing no special maintenance, and lasting a lifetime. The procedure is performed under local anaesthesia, takes 5–8 hours, and most patients return to routine within days.
At Big Derma, we combine advanced hair restoration science with artistic precision to deliver results that look completely natural, never artificial. Our expert-led doctor follows advanced FUE technology and creates a customized treatment plan according to your hair type, facial structure and long-term goals.We focus not just only on hair restoration, but also on restoring your confidence, safely, ethically, and with complete transparency every step of the way to our patient. At Big Derma hair transplant programme is led by board-certified dermatologists and trichology specialists with deep expertise in scalp health, follicle density mapping, and hairline design, ensuring every transplant looks natural, not operated.












Hair transplant is a surgical procedure, but it is far more straightforward than the word ‘surgical’ might suggest. There are no general anaesthetics, no hospital stays, and no dramatic recovery. You come in, get comfortable, and spend the day at the clinic while the procedure is carried out.

The science behind it is simple. Hair at the back and sides of your scalp the area called the donor zone is genetically programmed to stay. It does not respond to DHT the same way hair at the front and top does. When these follicles are moved to a thinning area, they carry that genetic resistance with them. They continue to grow permanently in their new location, just as they would have grown in the donor area.
During the procedure, the surgeon harvests individual hair follicles or a small strip of follicle-bearing skin from the donor zone, prepares them carefully under magnification, and then places them one by one into tiny recipient sites created in the balding area. The angle, depth, and direction of each placement matter enormously this is what separates a result that looks natural from one that looks operated. An experienced hand designs the hairline and places grafts to mirror the way hair naturally grows on that person’s scalp.
The procedure is done under local anaesthesia. You are fully awake but feel nothing in the scalp once the anaesthesia takes effect. Most people watch a film, listen to music, or just rest. After the procedure, you go home the same day. There are no stitches in the recipient area and the donor area heals on its own within a few days.
One of the biggest sources of anxiety around hair transplants is not knowing what to expect and when. People worry about the procedure itself, about the initial shedding, about whether the results are working. Here is exactly what the journey looks like honestly, and in the right order.
There are two main ways to harvest hair follicles for a transplant: FUE and FUT. Both produce natural, permanent results. The differences lie in how the donor area is managed, the volume of grafts that can be harvested, recovery time, and cost. Understanding the difference helps you have a more informed conversation with your surgeon because the right choice depends on your specific pattern of hair loss, not a blanket preference.

We assess before we advise. Every patient gets a trichoscopy evaluation before any treatment is discussed. This tells us the current state of your follicles, the extent and pattern of your hair loss, and whether a transplant is genuinely appropriate for you right now. Some patients we see are better served by medical management first. We are honest about this, even if it means not proceeding with a procedure.
The hairline is the first thing people notice. Getting it wrong — too straight, too low, or too dense at the very front — creates an immediately visible, artificial look. We treat hairline design as a clinical and artistic process, personalised to your face shape, age, and the natural frame of your features. Every hairline we design is different.
