What are the ingredients?

Actives: Minoxidil and/or Finasteride, Azelaic Acid
Base: TrichoSol
That's it. Nothing else. TrichoSol is a base made of primarily natural oils. Full a full breakdown of TrichoSol ingredients, please see below.
# Our Active Ingredients
Depending on your personalised prescription, your formula may contain one or more of the following clinically supported ingredients:
## 1. Minoxidil
**What it does:**
Minoxidil increases blood flow to the scalp and prolongs the growth (anagen) phase of the hair cycle. It is one of the most widely studied and clinically validated treatments for androgenetic alopecia.
**Purpose in LEO formulas:**
To stimulate hair follicles and promote regrowth in thinning areas.
---
## 2. Finasteride
**What it does:**
Finasteride reduces levels of DHT (dihydrotestosterone), the hormone responsible for male pattern hair loss.
**Purpose in LEO formulas:**
To slow or halt further miniaturisation of hair follicles by addressing the hormonal root cause of hair loss.
## 3. Azelaic Acid
What it does: Azelaic Acid is anti-inflammatory and anti-microbial. There's also some evidence to suggest it helps inhibit the activity of the enzyme 5-alpha-reductase, which converts testosterone into DHT (dihydrotestosterone).
Purpose in LEO formulas:
To provide additional support in reducing scalp inflammation, DHT activity, and improving scalp hygiene, helping protect hair follicles and support healthier hair growth.

# Our Base: TrichoSol (Alcohol-Free Delivery System)
Unlike many high-street formulations, LEO does not use high-percentage alcohol as a primary solvent.
Traditional alcohol-heavy bases can:
* Dry the scalp
* Cause irritation or flaking
* Damage the skin barrier
* Increase redness and sensitivity
Instead, LEO uses **TrichoSol**, a professionally formulated, alcohol-free vehicle designed specifically for scalp delivery.
TrichoSol enhances penetration while supporting scalp health.
