Shock Loss After Hair Transplant

Shock loss after the transplant is one of the less preferred consequences. Usually, people want to get a hairy look right after the procedure, yet all patients face more or less shock hair loss. Let us find out what the shock hair loss is? What are the reasons? When does it start? When does it pass?

What is the Shock Hair Loss and Why Does It Occur?

As mentioned, the FUE hair transplant is the extraction of grafts one by one from the donor area and their implant in the receiver area. These interventions are considered trauma, even if it is not very big. Capillary vessels that nourish hair roots are damaged during the surgery. The normal state of the skin and roots is affected, in other words, hair roots go through shock. Only ⅓ part of the hair nourishes it to live and when hair undergoes trauma, it tends to self-preservation.

Consequently, this hair root part stays under the skin causing a loss for the rest of the graft. In other words, it enters the winter sleep. This process is called shock loss after the hair transplant. In the medical literature, this condition is named telogen effluvium. It is one of the body’s defense mechanisms.

Additionally to that, candidates who face genetic hair loss problems may also lose roots which are to fall out as they are too weak and thin.

There are two types of hair loss after the hair transplant

  • Donor area hair loss
  • Recipient area hair loss

Hair Loss in the Donor Area

Hair loss in the donor area is a regular outcome. Especially too many grafts extraction from the above ear zone causes intense hair loss. This results in a bad hair transplant. A wide punch can also begin intensive hair loss. Usually, hair loss is often met in the FUE technique, while there are almost no such problems with the FUT

Hair Loss in the Recipient Area

Shock loss may occur during hair transplant in hairless areas or in density increase procedures. In this case, miniaturized hair can also fall out and this is the main subject on the current page.

When Does the Hair Loss Start and End?

The skin scrubs fall out 10 days after the surgery. A candidate has the desired look of the hair during this period, but it does not last long. In 15-20 days the hair starts falling out. Moreover, hair loss gets very intense on the 25th-30th day. For those who wonder how much time the shock loss lasts, the answer is around 2 months.

Moreover, hair loss intensity is different in every person. Some undergo it very less intense. Others lose almost all of the hair. This period is regarded as one of the most frustrating.

Pictures below show before hair transplant state and the shock loss after 3 months.

When Does the Lost Hair Grow Back?

The shock loss usually continues for 2 months. This period is not very pleasant and is called ‘the ugly duckling’. The problem in some patients lasts for 3-4 months. The very first hair is very weak and thin like baby hair.  You can find more information on this topic in our articles dedicated to after hair transplant and hair growth.

7 Factors that Influence Shock Loss

None of the patients wants to face shock hair loss, or undergo it at a lower range. There are some factors that increase or reduce shock hair loss. These factors are proved scientifically. However, the data was collected based on the statistics taken from operated hair transplants. It is worth remembering that there is no chance to escape from shock loss. Here are its factors:

  1. Age: The shock hair loss range is higher in younger people’s hair transplants. At the later ages, the androgenic tension decreases and this causes less hair loss. At earlier ages, medical treatment should be the first measure.
  2. Very Dense Hair Implant. Hair implantation more than adequate causes trauma for capillary vessels. As a consequence, the hair roots do not get nourishment and fall out.
  3. Parallel to Current Hairs. This is very important in density increase procedures. Newly implanted hair must be parallel to maintaining roots, otherwise, there will be damages causing hair loss.
  4. The angle of the Opened Channels. Too wide tips always mean bigger trauma. The more capillary vessels get damaged, the more hair ends falling out.
  5. Amount of Adrenaline. Adrenaline is usually used in the channel method to decrease bleeding. Moreover, local anesthesia also contains it. Inaccurate use of adrenaline increases the risk of necrosis and hair loss. As the pen implanter method does not require adrenaline, hair loss occurs in a low ebb. It is also important to avoid the injection of huge doses of local anesthesia to minimize shock hair loss.  Therefore, Tumescent anesthesia will develop shock
  6. Use of Finasteride and Minoxidil. The use of finasteride and minoxidil before and after hair transplantation has been proved to reduce shock loss.
  7. Mega Sessions. Big amount of hair extraction and implantation increases hair loss. Mega sessions mean significant trauma to capillary vessels and the use of a large amount of adrenaline. Additionally, extracted hair grafts remain outside for too long. The ideal number per session is 2.000 grafts. If there is a need for more, the operation can be split into several sessions

The picture below illustrates the state before hair transplant and shock loss in 15 days, 1 month, 3 months.

Will My Natural Hair Fall Out After the Hair Transplant?

Yes, there is such a possibility. Hair in telogen and catagen periods can fall out. Hair in this state would be lost anyway. Moreover, if the channels are opened with too wide punches, healthy hair may be damaged as well and fall out as a result

When Does the Implanted Hair Start Falling Out?

It is an individual question. Normally hair loss starts 15-20 days after the surgery.

May There Be No Hair Loss?

Sometimes, it happens. Shock hair loss is less met in a later age.

Is There Hair Loss in Women After Transplants?

Women face this situation more often. The reason is that they usually apply for density increase procedures. Moreover, hair in women is thinner. All in all, female hair transplant causes more trauma risks to natural hair.

What is the Shape of Lost Hair?

The hair is lost mostly in the shape of J or L (walking stick).

What Are the Reasons For Hair Loss in the Donor Area?

Unfortunately, the reason is the wrong hair extraction. When the amount of extracted hair is more than supposed to be, remaining natural hair also falls out. Minoxidil may help in returning the lost hair in the donor area. Sometimes, permanent hair loss occurs in that area.

Can All the Lost Hair Regrow?

In short, the answer is no. Some of the extracted hair can undergo telogen or catagen phases, this is why it may not regrow.

Is Hair Loss Normal After the Hair Transplant?

Yes, this is a general consequence of the hair transplants. Usually, it lasts for 45-60 days
