Natural DHT blocking hair oil

Treat the root cause of hair loss, without the side effects.

Androgenetic alopecia aka genetic hair loss, is the single leading cause of hair loss in people across the world. The usual advice is just hop on something like Finasteride, which works by blocking the production of DHT in your body. This will often work, however many people also tend to go through intense side effects. We formulated our DHT Defense blend with saw palmetto and pumpkin seed oil, which are natural DHT inhibitors.

The root cause

DHT takes your hair one cycle at a time.

Your body converts about 10% of its testosterone into DHT every day. At the temples and crown, it binds to the follicle roots and shrinks them. The change is gradual and subtle, which causes it to sneak up on people. Once you notice, it's time to act quickly. 

How people try to fix it

Hiding it

Hats, fibres, longer cuts. It covers the thinning while DHT carries on underneath.

Shampoos & oils

They feel like progress, but most never target DHT at all.

Finasteride

Blocks DHT, but needs a prescription and can bring sexual and mood side effects.

Minoxidil

Doesn’t touch DHT. Early shedding, irritation, and gains fade if you stop.

DHT Defense

Natural DHT blockers at the root. No prescription, no reported side effects.

For advanced cases of AGA, the use of pharmaceutical drugs may be required. Always consult with a doctor.

iii.

Scalp & circulationWent head-to-head with minoxidil 2% over six months: similar gains in hair count, with less scalp itching.

iv.

v.

Hair oil or beard oil?

The hair oil carries extra scalp and follicle ingredients. You can use the beard oil on your hair, but we don't recommend the hair oil on your face, as it may irritate the skin there.

Questions

Before you order.

How is this different from finasteride or minoxidil?

Finasteride is a prescription drug that blocks DHT throughout the body; minoxidil is a topical that acts on blood flow and the growth phase, not DHT. DHT Defense uses plant oils studied for inhibiting the same enzyme finasteride targets, without a prescription.

When will I see results?

Hair grows slowly, so this takes patience. Some people notice a difference in as little as 8–16 weeks, but for most it can take up to six months of consistent daily use. Take a photo on day one so you have something to compare against. That’s also why our money-back guarantee runs a full 180 days.

Can I use it alongside finasteride or minoxidil?

Many people add it to an existing routine. If you're on a prescription treatment, check with your doctor or pharmacist before adding anything new.

Will it make my hair greasy?

No. Grapeseed is the base because it's light and absorbs fast. The rosemary gives it a subtle, clean scent.

Any chance of irritation?

Mild irritation is possible if you're allergic to any of the plants in the blend. Patch test on your inner arm first; if irritation occurs, rinse with water.
