Hair Strengthening & Thickening Kit: How to Use It for Fuller, Healthier Hair

The Hair Strengthening & Thickening Kit from Azlok is a set of four nourishing oils—Jamaican Black Castor Oil, Rosemary Oil, Onion Oil and Black Seed (Kalonji) Oil—meant to be massaged into the scalp and hair to support stronger roots, reduce breakage and give hair a fuller look over time. Priced at ₹919, it works best when used consistently as part of a simple oiling routine rather than as a one-time fix.

What's inside the kit

Each oil in the kit plays a slightly different role, and together they cover scalp care, moisture and strength:

Jamaican Black Castor Oil (100 g): Thick and rich, it coats strands, seals in moisture and is traditionally used along the edges and roots for a conditioning effect.
Rosemary Oil (10 g): A concentrated essential oil often used in tiny amounts to freshen the scalp and add fragrance. It is potent, so it should always be diluted before use.
Onion Oil (50 g): Popular in Indian hair routines, onion-infused oil is used to massage the scalp and support the appearance of thicker hair.
Black Seed (Kalonji) Oil (100 g): A traditional oil valued for scalp conditioning and adding a natural shine to dull, dry hair.

All the oils are oil-soluble and free from harsh chemicals and artificial additives, which makes them suitable for most hair types.

How to use the kit

You can use the oils individually or blend them into one nourishing scalp oil. A simple routine looks like this:

In a small bowl, take about 2 tablespoons of Jamaican Black Castor Oil and Black Seed Oil as your base.
Add roughly 1 tablespoon of Onion Oil.
Add just 2 to 3 drops of Rosemary Oil—it is strong, so more is not better.
Warm the blend slightly by placing the bowl in warm water (never heat oils directly on a flame).
Part your hair and massage the oil into your scalp with your fingertips for 5–10 minutes, then work the remainder down the lengths.
Leave it on for at least an hour, or overnight, then wash out with a mild shampoo.

Two to three applications a week is a sensible starting point. Because castor and black seed oils are thick, you may need to shampoo twice to rinse fully.

Tips and safety notes

Natural does not mean risk-free, so keep these points in mind:

Patch test first. Apply a little diluted oil behind your ear or on your inner arm and wait 24 hours before using it on your whole scalp.
Always dilute rosemary oil. Essential oils are concentrated and can irritate skin if used neat.
Keep all oils away from the eyes and out of reach of children.
These oils are for external use only—do not ingest them.
If you are pregnant, breastfeeding or have a scalp condition, check with a doctor before starting.
Manage expectations: oiling supports scalp health and hair texture, but it is not an overnight cure for hair loss. Genetics, diet, stress and medical factors all play a part.

Buying and storage

The kit comes as a single pack, made in India, with a shelf life of about two years. Store the bottles in a cool, dry place away from direct sunlight, and keep the caps tightly closed to preserve freshness. If any oil changes smell noticeably or looks cloudy, it is best not to use it. Azlok packs the set for regular home use, so a little goes a long way if you measure carefully.

FAQ

How often should I use the Hair Strengthening & Thickening Kit?

For most people, two to three scalp massages per week works well. Consistency over several weeks matters more than using large amounts each time.

Can I use the oils on all hair types?

Yes, the kit is suitable for all hair types. If your hair is fine or oily, use smaller quantities and focus mainly on the scalp rather than the lengths.

Do I need to mix all four oils together?

Not necessarily. You can blend them for an all-in-one treatment or use them separately. Just remember rosemary oil is an essential oil and should always be diluted in a carrier like castor or black seed oil.

How long before I see results?

Hair care takes patience. With regular use, many people notice softer, shinier and more manageable hair within a few weeks, while changes in strength and volume develop gradually over months.

Is it safe to leave the oil overnight?

Yes, an overnight treatment is fine for most people. Protect your pillow with a towel and always do a patch test first to rule out any sensitivity.
