About the Liss Unlimited Range
Liss Unlimited is the Serie Expert range from L’Oréal Professionnel for frizzy, rebellious hair. L’Oréal says the range helps discipline hair for up to 4 days, based on its own instrumental test using the shampoo, mask and leave-in together.
The range is built around Pro-Keratin, and the leave-in serum adds Evening Primrose Oil. The aim is smoother, softer, shinier hair that is easier to manage in humid weather.
Liss Unlimited Routine: Shampoo, Mask and Serum
For the fullest effect, use the Liss Unlimited Shampoo to cleanse, the Liss Unlimited Mask to nourish, and finish with the Liss Unlimited Serum on the lengths before blow-drying.
Who Liss Unlimited Is Made For
Liss Unlimited suits frizzy, dry and unmanageable hair, especially hair that puffs up in humidity. It is a popular choice in hot, humid countries like Bangladesh.

How to Apply Liss Unlimited Serum
Apply a small amount to damp or dry lengths and ends. Warm it between your palms first, then smooth it over the hair from the middle down to the tips.
Keep it away from the roots so hair stays light and fresh. Do not rinse; style as usual.
Damp or Dry Hair?
On damp hair, a leave-in helps before blow-drying and gives a smoother finish. On dry hair, a tiny amount tames flyaways and adds shine during the day.
How Much Should You Use?
Start with one or two pumps. Short or fine hair needs very little, while long or thick hair may need a little more. Too much can make hair look greasy.
Using Liss Unlimited Serum Before Heat Styling
If you blow-dry or straighten, apply the leave-in first and then style. Always keep the dryer moving and avoid holding hot tools on the same section for too long.
Leave-In vs Traditional Hair Oil
Traditional oils are usually applied before washing and then washed out. A professional leave-in like this one is lighter and made to stay in the hair after washing, for smoothness and shine without a heavy feel.
Leave-In Care for Humid Days
On humid days, hair absorbs moisture from the air and can frizz quickly. A light leave-in on the lengths helps keep them smoother and more controlled while you are outside.
Protecting the Ends
The ends are the oldest and driest part of your hair. Concentrate the product there, and trim split ends regularly for a neater look.
Using a Leave-In on Curly or Wavy Hair
Curly and wavy hair can use leave-in care too. Apply a small amount to damp hair, scrunch gently and let it dry without too much touching to reduce frizz.
Texture and Feel
Professional leave-ins are designed to feel light, not greasy. If hair ever feels heavy, you are probably using too much; halve the amount next time.

Know Your Hair Type Before Using Liss Unlimited Serum
Hair that is frizzy, dry, fine, thick, coloured, chemically straightened or damaged each needs slightly different care. Look at how your hair behaves after washing: does it puff up, feel rough, tangle easily or lose colour quickly?
Matching the product to the problem is the key. Read the “Who should use” section on this page to see whether this product fits your hair.
Heat Styling Without Extra Damage
Blow-dryers, straighteners and curling tongs are a big cause of dryness and breakage. Let hair air-dry partly before blow-drying, use a medium setting, and keep tools moving.
Give your hair regular breaks from heat, and use a mask or leave-in care on the lengths to keep them smooth and easier to manage.
Monsoon Hair Care Tips
During the rainy season, humidity is at its highest and hair can frizz within minutes of stepping outside. Rain water and sweat can also leave the scalp feeling itchy or oily.
Wash your scalp regularly, dry hair properly before tying it up, and use smoothing care on the lengths. Avoid tying wet hair tightly, as it is weaker when wet.
Salon Hair Care vs Regular Shampoo
Professional ranges are made for specific hair needs, such as frizz, breakage, colour care or straightened hair, and are designed to be used together as a system. Regular supermarket shampoos are usually made for a broad, general audience.
That is why many people keep a salon range for their main routine. This product belongs to that professional category.
Gentle Habits for Healthier Hair
Detangle from the ends upwards with a wide-tooth comb, especially when hair is wet. Use soft hair ties without metal parts, and avoid pulling hair into very tight styles every day.
Sleeping on a smooth pillowcase and trimming split ends every few months also helps hair look neater and feel softer between salon visits.
Hair Care for Men and Women
Professional hair care is not only for women. Men with long hair, curly hair, coloured hair or a dry scalp can use the same products. Simply adjust the amount to your hair length.
Is Liss Unlimited Serum Worth It?
Professional hair care usually costs more than supermarket brands, but it is made for specific hair needs and is designed to work as a system. If the concern it targets is your main hair problem, a targeted product often gives a more noticeable difference than a general one.
Looking at cost per use also helps. A salon-size bottle or jar lasts many weeks, so the price per wash is often lower than it first seems.
How Long Until You See Results With Liss Unlimited Serum?
Some things, like softness and shine, can often be felt from the first use. Changes such as less frizz, less breakage or longer-lasting colour are best judged after a few weeks of regular use.
Results always depend on your hair type, its current condition, your water, your styling habits and the rest of your routine, so give the product a fair trial before deciding.
Using Liss Unlimited Serum on Chemically Treated Hair
Professional ranges are often used after salon services such as colour, keratin, smoothing or straightening. After any chemical treatment, ask your stylist how long to wait before the first wash and which products to use.
If your scalp is sensitive after a treatment, wait until any tenderness has settled before using new products.
Oily Scalp With Dry Ends
This is very common in hot weather. Focus shampoo on the scalp and keep masks, serums and oils on the mid-lengths and ends only. Rinse very well so no product is left at the roots.
Choosing the Right Size of Liss Unlimited Serum
Smaller bottles are good for trying a product or for travel. Salon sizes are better value once you know a product suits you, and they are handy for families or long hair.
If you travel, pour a little into a small clean travel bottle rather than carrying the large pack.

More Questions About Liss Unlimited Serum
Can men use Liss Unlimited Serum?
Yes. Hair care is not gender-specific. Choose it for your hair concern and adjust the amount to your hair length.
Can I use it with my regular hair oil?
Yes. If you oil before washing, shampoo twice to remove the oil fully, then continue with your usual routine.
Does it come with a pump or cap?
The pack type depends on the size. Check the photos on this page and the size option you choose.

Check it in front of the delivery person and record an unboxing video, then contact us straight away so we can help.
Hair Care Words Explained
Keratin is the main protein that hair is made of. Many professional products use keratin-inspired or protein ingredients to help care for damaged or processed hair.
Sulfate-free means the cleansing agents do not include sulfates such as sodium lauryl sulfate. Many people prefer sulfate-free cleansing after smoothing or keratin treatments.
A leave-in is any product you do not rinse out, such as a serum or oil. A rinse-off product, such as a shampoo or mask, is washed away after use.
Frizz is the fluffy, uncontrolled look hair gets when its surface is rough or when it absorbs moisture from humid air. Smoothing care aims to keep the surface flatter and more controlled.
A salon size is the large professional pack used in salons, usually 1 litre to 1.5 litres for shampoo or around 500g for masks. It costs less per use than a small retail pack.

Hair Care in Bangladesh Weather
Heat, humidity, monsoon rain, dust and sweat all affect hair in Bangladesh. Humid air makes many hair types swell and frizz, while sun, pollution and hard styling can leave lengths dry and rough.
That is why a routine built from matching products usually works better than random single items. Using this product as part of a steady routine, rather than now and then, is the easiest way to judge what it does for your hair.
Build a Salon-Style Routine With Liss Unlimited Serum
A simple professional routine has three steps: cleanse, treat and protect. Shampoo cleans the scalp and hair, a mask or conditioner smooths and nourishes the lengths, and a leave-in serum or oil finishes and protects.
You do not need every step every day. Most people shampoo two to four times a week, use a mask once or twice a week, and apply a leave-in only on the lengths when needed.
Common Mistakes to Avoid
Very hot water can dry hair and fade colour, so rinse with lukewarm water. Rubbing wet hair hard with a towel roughs up the surface; press and squeeze instead.
Using too much product does not give better results. Start with a small amount of this product and add more only if your hair is very long or thick. Always follow the directions printed on the pack.
How to Store Liss Unlimited Serum in Hot Weather
Keep the bottle or jar tightly closed, away from direct sunlight and heat. A cool, dry shelf is better than a sunny window or the top of a water heater.
Do not add water to the pack, and use clean, dry hands or a spatula for jars. Good storage helps the formula stay fresh until the last use.
Patch Test and Safety Tips
Hair products are for external use only. Avoid contact with the eyes, and if it happens, rinse with plenty of clean water. Stop using any product that causes itching, redness or irritation.
If you have a sensitive scalp, try a small amount first and wait a day. Keep all hair care out of the reach of children.
