Best Hair Growth Oil in the Philippines 2026: Top Picks for Thicker Hair

Organic castor oil is the most widely used natural hair growth remedy in the Philippines and globally — and Viva Naturals Organic Castor Oil is one of the most consistently reviewed options available locally on Shopee. The cold-pressed, hexane-free formula preserves the full ricinoleic acid content of castor oil, which is the fatty acid responsible for its anti-inflammatory and scalp-nourishing properties.

Massage 5–8 drops into the scalp 2–3 times weekly, focusing on the hairline and thinning areas. The thick consistency is best diluted with a lighter carrier oil (like argan or coconut) at a 1:1 ratio if you find it too heavy. Leave on for at least 30–60 minutes or overnight for deeper penetration, then shampoo out thoroughly.

Consistent use over 8–12 weeks shows improvements in scalp health and reduced breakage — the primary drivers of the hair fall cycle.

Mamaearth Onion Hair Oil combines onion seed extract (a concentrated source of sulfur that strengthens hair bonds) with castor oil, bhringraj, and redensyl — a combination designed to address multiple causes of Filipino hair fall simultaneously. Sulfur from onion extract is clinically associated with improved hair strength and reduced breakage, while redensyl is a patented ingredient shown to activate dormant hair follicles.

The formula is lighter than pure castor oil and absorbs into the scalp without extreme greasiness. Warm the oil slightly and massage into the scalp for 5 minutes before applying to hair lengths. Leave for 30–60 minutes before shampooing. The onion scent dissipates after washing and does not linger on dry hair.

Widely reviewed on Shopee Philippines, Mamaearth Onion Hair Oil has become one of the most popular hair growth formulas for Filipinos looking for a step up from basic castor oil.

Jamaican Black Castor Oil (JBCO) is distinct from regular castor oil — it is made by roasting castor beans before pressing, which produces a darker oil with higher ash content and a different pH profile. The alkaline pH is particularly effective at opening the hair cuticle on thick, coarse Filipino hair, allowing nutrients to penetrate more deeply than with regular castor oil.

JBCO is the preferred choice for Filipinos with thick, natural, or 4B/4C hair texture — common in Filipino communities with Aeta ancestry or mixed heritage. The high ricinoleic acid content promotes scalp circulation while the alkaline pH helps with scalp buildup common in areas with hard water (Metro Manila in particular).

Expect a thick, rich consistency that is best applied warm. Mix with argan or coconut oil at a 1:1 ratio for easier application and removal on long, thick Filipino hair.

The Ordinary disrupted the skincare market with potent clinical ingredients at accessible prices, and their Multi-Peptide Serum for Hair Density brings that same philosophy to scalp care. The formula contains CAPIXYL (a combination of acetyl tetrapeptide-3 and red clover extract), REDENSYL, PROCAPIL, and AnaGain Nu — a curated stack of clinically-supported peptides and botanical actives that address multiple stages of the hair growth cycle.

Unlike oils that primarily nourish from the outside, this serum works at the follicle level — stimulating anagen (growth) phase duration and reducing premature transition to catagen (resting) phase. In the clinical literature behind its key ingredients, subjects saw statistically significant improvements in hair density and thickness after 3 months of use.

Apply directly to a dry or damp scalp — do not rinse out. Use once or twice daily for best results. It's a lightweight, water-based serum that does not feel oily or require post-washing.
