With a remarkable Yuka score of 93/100, this hair oil treatment stands out as one of the safest and most effective options on the market. In this comprehensive review, we'll break down everything you need to know about this cult-favorite product.

What is OGX Renewing + Argan Oil of Morocco Penetrating Treatment?

The OGX Renewing + Argan Oil of Morocco Penetrating Treatment is a lightweight, concentrated hair oil designed to restore shine, strength, and softness to damaged hair. Formulated with Moroccan argan oil—often called "liquid gold"—this treatment penetrates deep into hair strands to repair damage from heat styling, chemical treatments, and environmental stressors.

Unlike heavy leave-in conditioners, this penetrating treatment absorbs quickly without leaving a greasy residue. It's part of OGX's signature Renewing + Argan Oil of Morocco collection, which has become a staple in bathrooms worldwide for its salon-quality results at an affordable price point.

What makes this product particularly noteworthy is its exceptional safety profile. With an outstanding Yuka score of 93/100, it's classified as "Excellent," meaning it contains minimal risky ingredients and prioritizes both efficacy and consumer health.

Yuka Score Analysis: 93/100 - What Does It Mean?

The Yuka app evaluates personal care products based on their ingredient safety, assigning scores from 0 to 100. A score of 93/100 places the OGX Argan Oil Penetrating Treatment in the "Excellent" category, indicating that it contains predominantly safe, risk-free ingredients with minimal health concerns.

This exceptional rating is particularly impressive for a hair treatment product, as many conventional hair care items contain questionable silicones, sulfates, and synthetic additives that can trigger allergic reactions or long-term health concerns. The fact that OGX has formulated a highly effective treatment while maintaining such a clean ingredient profile demonstrates their commitment to both performance and safety.

Here's what contributes to this excellent score:

• Predominantly risk-free ingredients: The majority of the formula consists of safe, well-tolerated components
• Transparent ingredient disclosure: All ingredients are clearly listed, allowing consumers to make informed decisions
• Minimal allergens: Only fragrance is flagged as a potential low-risk concern for sensitive individuals
• No harmful chemicals: Free from parabens, sulfates, and other controversial ingredients common in hair care

Complete Ingredient Breakdown

Understanding what you're putting on your hair is crucial for making informed purchasing decisions. Let's examine each ingredient in the OGX Argan Oil Penetrating Treatment and its function:

Dimethicone (Risk-free)

Dimethicone is a type of silicone that creates a protective barrier on hair strands, locking in moisture and creating a smooth, frizz-free finish. Despite some misconceptions about silicones, dimethicone is considered safe and non-toxic. It helps seal the hair cuticle, preventing moisture loss and protecting against heat damage from styling tools.

Isopropyl Myristate (Risk-free)

This lightweight emollient helps the product spread evenly through your hair while adding softness and shine. Isopropyl myristate enhances the absorption of other beneficial ingredients, allowing the argan oil to penetrate deeper into the hair shaft. It's non-comedogenic and considered safe for topical use.

Dimethiconol (Risk-free)

A heavier-weight silicone compared to dimethicone, dimethiconol provides long-lasting conditioning benefits and helps repair split ends. It creates a more substantial protective coating on damaged hair, making it ideal for treating severely compromised strands. This ingredient is safe and widely used in professional hair care products.

C12-15 Alkyl Benzoate (Risk-free)

This is a lightweight, dry-feeling emollient that prevents the greasy texture often associated with hair oils. It improves the spreadability of the product and helps achieve that coveted silky finish without weighing hair down. C12-15 alkyl benzoate is derived from benzoic acid and is considered completely safe.

Argania Spinosa Kernel Oil - Argan Oil (Risk-free)

The star ingredient! Argan oil is extracted from the kernels of the Moroccan argan tree and is packed with essential fatty acids, vitamin E, and antioxidants. It's renowned for its ability to:

• Deeply nourish and hydrate dry, brittle hair
• Repair damage from chemical treatments and heat styling
• Add brilliant shine without greasiness
• Protect against UV damage and environmental stressors
• Reduce frizz and improve manageability
• Strengthen hair and prevent breakage

Fragrance/Parfum (Low risk - Potential allergen and irritant)

The only ingredient flagged with even minimal concern is fragrance. While the scent is one of the beloved features of this product—a warm, exotic Moroccan-inspired aroma—synthetic fragrances can occasionally cause sensitivity in individuals with fragrance allergies or very reactive skin.

However, Yuka classifies this as only a low risk, meaning that for the vast majority of users, the fragrance poses no health concerns. If you have known fragrance sensitivities, you may want to patch-test this product first or opt for fragrance-free alternatives.

Who Should Use OGX Argan Oil Penetrating Treatment?

This versatile treatment works beautifully for a wide range of hair types and concerns:

• Curly and wavy hair: Enhances definition while controlling frizz
• Those seeking safer beauty products: The excellent Yuka score makes this a smart choice for health-conscious consumers

May not be ideal for:

• Very fine or thin hair: The silicone-rich formula might be too heavy for delicate strands
• Oily scalp/roots: This treatment is best applied to mid-lengths and ends to avoid greasiness

How to Use OGX Argan Oil Penetrating Treatment

Getting the best results from this product requires proper application technique. Here's how to use it effectively:

Method 1: Intensive Treatment (Recommended weekly)

1. Start with freshly washed, towel-dried hair
2. Dispense 1-2 pumps (depending on hair length and thickness) into your palm
3. Rub hands together to warm the oil
4. Apply to mid-lengths and ends, avoiding the roots and scalp
5. Comb through with a wide-tooth comb to ensure even distribution
6. Leave in for 5-10 minutes for deep penetration
7. Style as usual—no need to rinse

Method 2: Daily Styling Aid

1. Use on damp or dry hair
2. Dispense a small amount (start with 1/2 pump and add more if needed)
3. Warm between palms
4. Smooth through mid-lengths and ends
5. Style as desired

Method 3: Overnight Deep Conditioning

1. Apply generously to dry hair before bed
2. Braid or wrap hair in a silk scarf to prevent pillow transfer

4. Shampoo and condition as normal in the morning
5. Use this method once every 1-2 weeks for severely damaged hair

Pro tip: Less is more with this concentrated formula. Start with a small amount and build up as needed. You can always add more, but using too much will require washing to remove excess oil.
