Author : Sasha King | Published On : 04 Sep 2021

Hair loss to a certain extent is a normal process with a constant cycle of re-growth.  However, with certain factors like age, medications,  family history, hormonal changes, medical disorders, poor diet, adverse effects of medical treatments such as chemotherapy, or stress, hair loss can become rapid and permanent. 

Medications, hair transplant surgery,  PRP, Stem-Cells and laser therapy are promising options for various stages of hair loss.  Today, we discuss Laser Light Therapy For Hair Loss. 

What is a laser cap for hair loss?

Laser devices for Hair Loss Treatment come in multiple formats, including hats, helmets, caps, and headbands.  Typically, there are referred to as Low-level laser therapy (LLLT) which is intended to stimulate the scalp and hair follicles. Low-level laser therapy uses lower-power lasers that releases energy into the scalp. The light emitted is in the red or infrared region and are thought to stimulate cellular metabolism, blood flow and nutrient inflow into the targeted regions according to Davis Hair Restoration.

Is It Real?

Although various laser helmets on the market have received FDA safety approval, no efficacy trials have been done.  Basically, the device won't likely cause harm, but there is insufficient data to support its usefulness.  That doesn't mean it doesn't work, it's just that not enough rigourous studies have been conducted in a blind fashion to prove efficacy.  That is the case for many useful items including hair loss (exosomes, PRP come to mind!).   The study of whether low-level laser hair devices are useful for specific hair loss problems is ongoing.

Importantly, Laser hair restoration devices are not for everyone and should be discussed with a hair loss specialist before purchse. 

If you have made the purchase or seriously considering it, it is important to have patience.  A laser hair cap along with other measures like PRP or medications like Rogaine need to be consistently used for several months before any notieable effects are seen.  It's probably best to log your journey using photos for before and after results to monitor your progress.  The changes maybe subtle, but some expectations may include thicker and fuller hair growth.  It's unlikely to benefit complete hair loss regions.  

Here are some Pros and Cons about Laser Light Therapy For Hair Loss


Positive impacts of laser treatment

  • It's non-invasive
  • It's painless
  • It is considered safe
  • It can be used along with other hair loss methods for combination treatment

Negative impacts of laser treatment

  • Time-consuming: Treatment often requires multiple sessions each week for several months, and in some cases, for the rest of your life.
  • Still expensive and in conjunction with other therapies, the cost can add up.
  • Lack of efficacy trials to prove the merits of LLLT

The final decision about using LLLT for hair loss is a personal choice.  Hair transplant , PRP, exosomes are more expensive considerations and should be discussed in detail with a hair treatment specialist. For a personalized discussion, consider seeking out advice from a trusted source or reputable FUE hair transplant near me.   Sometimes, the therapies are used in conjunction for a more complete effect.
