DHT Blocking Shampoo FAQ’S

Any hair loss/hair thinning regimen requires a solid foundation. That starts with a quality shampoo that contains no sulfates, no parabens, no silicones and no artificial ingredients.  It should also contain ingredients designed to remove DHT from your scalp–the enzyme that causes hair loss and hair thinning in both men and women.  The Hair Restoration Laboratories DHT Blocking Shampoo is that foundation!

If you are not yet experiencing hair loss, or just beginning to, the Hair Restoration Laboratories DHT Blocking Shampoo is an excellent way to help delay the progression of hair loss.

What Is DHT And Why Does Removing It From Your Scalp Help Reverse Hair Loss?

Male and female pattern baldness is an extremely common condition. It is well established that the main culprit behind genetic hair loss is Dihydrotestosterone, abbreviated as DHT.  DHT is a hormone that is produced from testosterone.

When testosterone combines with 5-alpha-reductase (an enzyme involved in steroid metabolism), this results in the production of DHT.

Unfortunately, DHT causes havoc for hair follicles.  It connects to the androgen receptors at the base of the hair follicles.  This leads to miniaturization of the hair follicles and, eventually, hair thinning and loss.

In order to reverse hair loss, the DHT needs to be removed from the body.  There are certain medications that help reduce the amount of DHT from your body, but they are only prescribed for men (i.e., finasteride).  Even if you are taking these medications, supplementing them with a topical DHT blocker will boost your efforts to fight hair loss.  And, if you are not taking such medication, you can also help block DHT by the use of a shampoo that contains ingredients that can inhibit 5-alpha-reductase. As a result, this blocks DHT from connecting to the scalp’s androgen receptors and prevents hair loss and hair follicle miniaturization.

The Hair Restoration Laboratories DHT Blocking Hair Loss Shampoo contains a number of ingredients (described below) that studies establish have the ability to inhibit the activity of 5-alpha-reductase, thus helping to reverse hair loss and regrow healthier, stronger, hair.

What Are Some Of The Ingredients That Make The DHT Blocking Shampoo So Unique And Effective?

  •  Salvia Miltiorrhiza Root Extract
  • Studies establish that this extract improves blood circulation to the hair follicle.
  • Ligusticum Chuanxiong Root Extract
    Studies establish that this extract has a beneficial effect on hair, reduces hair loss, makes hair silky, glossy and manageable.
  • Astragalus Membranaceus Root Extract
    Known for its adaptogen properties, this extract is rich is polysaccharides, which are nutrients critical to hair follicle health.


  • Camellia Japonica Seed Oil
    In research studies, this extract has demonstrated potent antioxidant properties with the ability to inhibit the production of DHT.
  • Argania Spinosa Kernel Argan oil
    A natural oil that is rich in vitamin E and essential fatty acids. This ingredient provides extensive conditioning and helps combat hair dryness and damage, in addition to diminishing frizz.
  • Biotin (Vitamin H) 
    An essential B-vitamin that promotes hair growth and aids in overall hair health. This ingredient strengthens both the hair follicle and the hair shaft, from which the hair grows.


  • Soy Isoflavones
    Studies establish soy isoflavones promote hair growth by increasing dermal levels of insulin-like growth factor (IGF-1).
  • Tocopherol
    Also known as Vitamin E, this ingredient is an antioxidant and intensive hair conditioning vitamin. This ingredient also softens the hair, provides essential healthy-hair nutrients, and soothes & protects the scalp.
  • Nicotinic Acid/Niacin
    Niacin and hair growth go hand in hand because this B vitamin boosts energy and improves blood flow to the scalp. A healthy scalp is crucial for healthy hair growth.
  • Nigella Sativa Oil
    Studies established that sativa increased hair growth and was effective in treating telogen effluvium, a hair loss condition primarily experienced by women.
  • Hibiscus Rosa-sinensis Extract
    Studies of this leaf extract promoted more hair follicles in the anagen (growth) phase.


  • β-sitosterol
    There are several reasons that may explain why phytosterols can be helpful in the treatment of hair loss. One of their main characteristics is their anti-inflammatory properties. Inflammation is often one of the characteristics of the alopecia scalp and several studies have shown that phytosterols have great anti-inflammatory purposes.
  • Citrus Medica Limonum Oil
    A fragrant natural oil that is rich in Vitamin C and is a powerful antioxidant that helps protect the scalp and hair from free radical damage.
  • Polygonum Multiflorum Root Extract
    Studies establish that this extract may be a highly effective anti-androgen through decreasing DHT amounts in your body by obstructing five alpha-reductase digestive enzymes.
  • Rosemarinus Officinalis Leaf Oil
    In certain studies, rosemary oil was just as effective a minoxidil.  It helped alleviate itchy scalps more successfully than minoxidil and stimulated hair growth.


  • Cedrus Atlantica Bark oil
    Subjects in a control group whose scalps were massaged with this oil saw a 15%-50% improvement in hair loss.
  • Phyllanthus Emblica
    Studies confirm that this herb is a potent 5α-reductase inhibitor and hair growth promoter.


Can The DHT Blocking Shampoo Be Used With Minoxidil?

Absolutely.  Unfortunately, studies repeatedly reflect that minoxidil only works for a small percentage of its users.  And, for those who it benefits, it is more likely to slow the progression of hair loss, rather than actually regrow meaningful hair.  If you are using minoxidil, supplementing it with a product that has the ability to remove DHT and other toxins from your scalp can be essential to promote maximum absorption of the minoxidil active ingredients, thus increasing its effectiveness.

Can The DHT Blocking Shampoo Be Effective Without Prescription Drugs?

Yes.  The primary cause of hair loss is genetic.  When hair loss is caused by genetics, the presence of DHT in the hair follicle and scalp is almost always to blame for hair miniaturization.  Hair miniaturization is a phenomenon in which strands of hair become thinner, shorter, more brittle or weak with each successive progression through the hair cycle.  Over time, the miniaturization process leads to the appearance of thinner hair and hair loss.

By helping to remove DHT from the scalp, the Hair Restoration Laboratories DHT Blocking Shampoo can assist in reversing and delaying the miniaturization process.

Can The DHT Blocking Shampoo Be Used By Men And Women?

Yes.  The DHT Blocking Shampoo can be used by men and women on a daily basis.  All adults seeking to prevent or reverse hair loss will benefit from the shampoo, as it is free from sulfates, parabens, silicones and artificial ingredients.  As with any hair loss regimen, it is recommended that you consult with your physician before commencing use of the DHT Blocking Shampoo.

How Should I Use The Shampoo

The shampoo should be used daily and left on your scalp for a period of 3 to 5 minutes to allow for maximum absorption of the DHT-blocking ingredients. Your hair’s appearance will improve after the first use and hair loss benefits will be noticeable within a period of 3 to 5 months.  If you experience any irritation from the shampoo, please discontinue its use.

Laser Helmet FAQ’S


What is Low Level Laser Therapy (LLLT)?

Low Level Laser Therapy (LLLT) is also referred to as red light therapy, soft laser, laser stimulation, photo laser modulation and cold laser. Many studies establish that LLLT is an effective way for men and women to treat and reverse hair loss and hair thinning caused by multiple factors, such as genetics, stress, medication, overuse of styling products and environmental factors.

In 1966, Hungarian physician Endre Mester published an experiment in which he observed hair growth in rats treated with laser therapy.  Over the next fifty (50) years, numerous studies and clinical trials reiterated that LLLT is an effective treatment for hair loss.  In 2007, the Food and Drug Administration first approved LLLT for hair loss.

The Hair Restoration Laboratories Laser Helmet utilizes 200 real, independent laser diodes (no led lights) that are stored in a sealed semicircle helmet. The Laser Helmet is powered by an internal lithium battery, so there are no dangling cords to worry about.  You can use the Laser Helmet anytime, anywhere.  While you wear it, the 200 independent lasers are hard at work striving to improve your hair quality, reverse hair thinning and restore your hair!

Who is fit to use LLLT?

Many studies confirm that LLLT is an effective treatment for both men and women. 

While there are many different types of hair loss, the most common type is androgenetic alopecia, also called pattern baldness.  In men, pattern baldness tends to commence with a receding hair line, followed by hair thinning in the crown, or back of the scalp.  In women, pattern hair loss is generally different and tends to be more dispersed throughout the top of the scalp.

Studies have confirmed that LLLT is effective for all pattern baldness, including a receding hairline, thinning hair, and diffuse hair.  It also is effective in reversing hair loss caused by stress, medication and post-partum issues. The Hair Restoration Laboratories Laser Helmet is absolutely the BEST solution for individuals who are or are not using other products for the treatment of hair loss. The Laser Helmet is effective by itself or in conjunction with other FDA-approved treatments.


How Does LLLT Work?

The hair rejuvenation cycle has three stages:

1. The growth phase which is also referred to as the anagen phase

2. Resting phase or the telogen phase

3. The shedding phase or catagen phase.

LLLT helps to boost the flow of blood in your scalp as well as stimulate cellular metabolism in the telogen or the catagen phases which leads to the growth of a healthier, stronger and new (anagen) hair.

What are the benefits of LLLT?

LLLT is an exceptional option to treat hair loss because it has no known side-effects.

While there are medications which have been approved for the treatment of hair loss, both can cause serious side effects.   Finasteride (Propecia) is an oral medication that is only approved by FDA for use by men.  It has been reported to cause a variety of side-effects, from sexual to swelling, dizziness, and may cause decrease in blood prostate specific antigen (PSA) levels that can affect PSA blood test results used to detect prostate cancer.

Minoxidil (Rogaine) which has been approved for men and women, also can have side-effects, including scalp irritation, dizziness, and unwanted hair growth on face. Once started, both finasteride and minoxidil must be used be used for life.  Once stopped, any hair grown or preserved through these medications will be lost.

The Hair Restoration Laboratories Laser Helmet is easy to use.  Based on its internal rechargeable battery, it can be used anywhere, while you go about your everyday activities.

It does not require application of any lotions or solutions that can interfere with the style of your hair.

It can be used in connection with other hair loss treatments.   However, studies also establish that it can be extremely effective on its own.
