For a baldness level 2, where hair loss is relatively mild, the number of grafts needed may be lower compared to more advanced stages of baldness. Generally the cost is determined by the number of hair grafts required to cover the affected area.

In Hair transplant, one has to remember a few things-

1. Hair transplant is an ART. A natural result is very important. We take care of that by ensuring absolutely natural angles and directions of the transplanted grafts.

2. Equally important is density (how many grafts are transplanted per square centimetre). In 25 years of my experience, I have found that no one is satisfied by a low density hair transplant.

A great hair transplant, therefore, is one where the patient puts forward his choice of hairline design, on the one hand, and the doctor gives a natural look as well as the best possible density using all the available grafts from the patient's scalp, beard and body donor areas.

For the remaining areas, where the patient is noticing early hairfall or diffuse thinning, it's important to improve the epigenome of the patient.

Epigenome can be best described as the inner environment of the body, especially, around our genes. Epigenome is affected by a wide variety of things including diet, exercise, stress, illness, pollution etc. A stressed/flawed epigenome is why we find :

1. People losing hair 10 years before their previous generations.

2. Hairfall is preceded by an adverse event like an illness or change of diet, water or location.

Till recent times, doctors did not use to pay attention to these factors, taking them to be incidental in a disease largely governed by our genes.

However, correcting these epigenetic anomalies goes a long way in reducing or even reversing hairfall.

Epigenetic measures are more personalised according to patient history and involves feeding the hair follicle roots/stem cells by a microneedling based, home-use approach.

One of the reasons that beard hair growth is such an individualized matter can be genetic factors, as well as hormonal imbalances or other medical conditions. In your situation, if you are interested in fullness, some facial hair treatments could be considered. These include topical medications, oral supplements, or surgical beard transplants.  To consult a dermatologist or a qualified expert about your specific issues and the options available that are right for you.

40000 graft is a myth or may be wrongly heard. At max around 2500-3500 grafts can be implanted in one session and maximum 4000-4500 grafts may be implanted in two sessions. I have no idea about Chennai but surgery might take upto 6-8 hrs. and this varies from clinic to clinic.

While FUT procedure involves taking a thin strip of skin from the back of the head, the FUE procedure is more minimally invasive as it involves small punches made with 0.7 to 0.8 mm punches in the donor area.

Hair loss is something that can happen due to several factors. However, the main reasons for this occurrence are the intensity of the hair, the distribution of hairs, the underlying disorders, and genetics. A few symptoms of hair fall include either a bigger size comb or more hair on your clothes that are normally covered in hair and thinning of hair. Assess your diet and get enough rest. Be gentle on your hair using soft hair care products and don't do tight hairstyles. If the problem progresses then ask a dermatologist for help.

 FUT scars cannot be permanently removed but we can definitely minimize it's visibility

There are two options

One is scalp micro pigmentation and the other is FUE method of transplant on the FUT scar

Right now Treatment has to be only addressing hair fall, with proteins in diet, anti hair fall supplementations, going light on shampoos and conditioners .After the sudden hair fall has got arrested then hair thinning can be addressed and later after consulting dermatologist, he can decide hair transplant is required on not.

One of the factors that influence eligibility for a hair transplant includes age. Although there is no strict age limit, the stability of your hair loss pattern should be considered. Typically, hair transplants will be recommended for individuals whose menu of baldness is stabilizing around their late 20’s or older; this gives them a better sense about what the future patterns would look like. Furthermore, overall health, availability of donor hairs and rational expectations surrender to a decision on eligibility.

Taking his age into consideration I can suggest Advance PRP or Regenra
